Question

drop a ball out of a window 1 m above the ground while traveling down the road at 18m/s. how far horizontally will the ball hit the ground. and where will the car be in relation to the ball when it lands?

Answer 1

In the y direction V initial is 0m/s, and you can find V final by using gravity as -9.81 m/s^2. After you find final velocity, find time it takes to reach the ground using \[\Delta(t)=(2\Delta(y))\div(-V)\] . After you find time, you can assume that the ball has no acceleration or deceleration in the x direction, so the distance it covers can be found by using \[\Delta(x)=V \Delta(t)\] . If the car and the ball are moving at the same speed when the ball is dropped the ball and the car should be at the same spot the ball hits the ground when it does.
