A and B start at the same place and direction. A decelerates with an initial speed of 16m / s and an acceleration of 2m / s, and B decelerates with an acceleration of 2m / s 4 m / s initial velocity, 1 m / s Square acceleration, find 1. The maximum distance between two vehicles before they meet again? 2. The time required for two vehicles to meet again? Can we use equations in mathematics,

Because one is to slow down and the other is to accelerate
So when we find the maximum distance between the two, the speed of the two is equal
That is, when 16-2t = 4 + T
That is, t = 4
X a = 16 * 4-16 = 48
X B = 16 + 8 = 24
X relative = 24m
When they meet, their displacement is the same
16T-T^2=4T+1/2 *T^2
T=0 ,T=8
It's meaningful because it stops at 8s
So 1.24M
2.8s
Isn't this an equation with unknowns t?
Do you need formulas to solve math problems
