Question

6. MJ 19/P21/Q10
An object falls from the top of a building that is 25 m high. Air resistance is negligible
What is the speed of the object when it hits the ground?
C 25 m/s
B
22 m/s
D 625 mis
A 10 m/s​

Answer 1

Answer:

From the question:

Initial velocity, u=0

Height of the building, h =25m

Acceleration due to gravity, g =10m/

v ²+u ²=2gh

v ²=2gh [as initial velocity is 0]

v= √2gh

= √2×10 x 25

= √500

=22.36m/s ≈ 22m/s
