Question

An egg falls out of a nest of a tree. It freefalls for 1.5 seconds, and then hits the ground. From how high up did the egg fall?

Answer 1

Answer:

11.025m

Explanation:

Using kinematics,

u = Initial velocity = 0.

t = Time taken = 1.5sec.

a = Acceleration from gravity = 9.8m/s^2

Distance = s

= ut + 1/2 * a * t^2

= 0 + 1/2 * 9.8 * (1.5)^2

= 11.025m

Answer 2
