Someone in a car going past you at the speed of 35 m/s drops a small rock from a height of 1.5 m. How far from the point of the drop will the rock hit the ground? The acceleration due to gravity is 9.8 m/s2.

Question

Answer in units of m.

Answer 1

Xo = 35 m/s.
h = 1.5 m.

h = 0.5g*t^2 = 1.5 m.
4.9t^2 = 1.5
t^2 = 0.306
Tf = 0.553 s. = Fall time.

Dx = Xo*Tf = 35m/s * 0.553s = 19.4 m.

Answer 2

Someone in a car going past you at the speed of 39 m/s drops a small rock from a height of 1.9 m. How far from the point of the drop will the rock hit the ground? The acceleration due to gravity is 9.8 m/s2
