Physics in grade one of senior high school: description of speed of motion -- speed The average velocity of an object passing through two consecutive equal displacements is V1 and V2 respectively, and the average velocity in the whole process is v = 12m / s. given V1 = 10m / s, the size of V2 can be calculated Give the operation process, thank you!
Let the total displacement be x0, x0 / 2 = X1 = x2
x1/v1+x2/v2=x0/v
If we omit all x, we have to:
1/20+1/2v2=1/12
The solution is: V2 = 15m / s

Pull an object with force F to make it move in a straight line with uniform acceleration on the horizontal plane with acceleration a. the horizontal component of force F is F1, as shown in the figure. If the force F & cent; with the same size and direction as F1 is used to pull the object instead of F to produce acceleration a & cent;, then: (b c) A. When the horizontal plane is smooth, a & cent; < a B. when the horizontal plane is smooth, a & cent; = a C. When the horizontal plane is rough, a & cent; < a D. when the horizontal plane is rough, a & cent; = a D Please explain why when the plane is smooth, a is the same. F1 is obviously less than f, so its horizontal component is also less than f's horizontal component?
