Physics problems in grade one of senior high school If a gymnast falls from a certain height, his center of gravity will drop about 15cm when his feet fall to the ground. What is the maximum limit height of a gymnast's jump? It's better to have a detailed explanation

V end & sup2; - V beginning & sup2; = 2As
V end & sup2; - 0 = 2 * 20g * 0.15
V end & sup2; = 2GH open radical = 2 * 20g * 0.15 = 60
h=3
So, the maximum height is three meters
Because it's not easy to input all kinds of symbols, if you don't understand, you can leave a message for me

1. Physics of grade one in Senior High School: the direction of velocity and acceleration in uniform acceleration motion and uniform variable speed motion Physics of grade one in Senior High School: the direction of velocity and acceleration in uniform acceleration linear motion and uniform variable speed linear motion In the uniformly accelerated linear motion, the direction of acceleration is not changed. Since it is an accelerated motion, the direction of velocity is the same as that of acceleration, that is, the direction of velocity displacement acceleration is the same? In the uniform speed change linear motion, is the uniform speed change either uniform acceleration or uniform deceleration? Is the direction of the velocity displacement acceleration of the uniform speed change linear motion the same? In a uniformly accelerated linear motion, the direction of acceleration remains unchanged. Is it true that since it is an accelerated motion, the direction of velocity is the same as that of acceleration, that is, the direction of velocity, displacement and acceleration is the same? In the uniform speed change linear motion, is the uniform speed change either uniform acceleration or uniform deceleration? Is the direction of the velocity, displacement and acceleration of the uniform linear motion the same? Break a sentence··
2. For a particle moving in a straight line with uniform velocity variation, the greater the velocity variation in the same time, the greater the acceleration
3. When an object is moving in a straight line with constant speed change, does the acceleration change equally in the same time
4. The definition of uniform variable speed linear motion is the same acceleration, that is to say, as long as the speed change / time change is the same? Look at it The definition of uniform variable speed linear motion is the same acceleration, that is to say, as long as the speed change / time change is the same? Don't stress that the speed change must be the same in the same time, as long as the ratio is the same? That is, the speed change in two seconds is four meters per second, and the speed change in four seconds is eight meters per second. So the acceleration is the same, so is he still moving in a straight line with constant speed?
5. For uniform linear motion, the acceleration change is the same in the same time Why is this sentence wrong? I know it's invariable. Isn't it a constant function? In the same time change is not 0? 0 is not the same?
6. "The uniform speed change linear motion is the linear motion whose displacement changes uniformly with time". Is that right? Why
7. The relationship between the distance and time for a car to make a uniform acceleration straight-line motion from standstill can be expressed as s = half a * (the square of T), where a is the acceleration. In one driving, the acceleration of the car is 5m / s, then the time required for a 75 meter journey is () Accurate to 0.1s
8. The relationship between the coordinate X of the particle moving on the x-axis and time t is x = 3T & sup2; + 2t-4, and the acceleration is, when t = 0,
9. When a particle moves along the x-axis, the relationship between its acceleration a and the position coordinate X is a = 2 + 6x2 (a is equal to the square of 2 plus 6 x), if the velocity of the particle at the origin is zero Try to find the speed at any position. (I can't calculate the second-order differential, please write in detail, I'm stupid.)
10. Question 6: if the particle moves in a straight line s = 5T square + 3t-1, then the velocity V (2) =? Acceleration α (2) =?

12. Please prove that the displacement difference of an object moving in a straight line with uniform speed change is a constant value in any two consecutive equal time periods. Let the acceleration be a and the time periods be continuous and equal If t is t and the displacement difference is Δ x, then Δ x = the square of a * t
13. It is proved that: (1) if the difference of displacement of an object moving uniformly in a straight line is a fixed value in any two continuous equal time, and the acceleration is a, the continuous equal time is t, and the difference of displacement is △ x, then △ x = at2. (2) in the uniformly variable linear motion, the instantaneous velocity at the midpoint of displacement is VX2 = V20 + v2t2
