Question

A ball is falling from a building. What will be the speed if it has falling for 220m​

Answer 1

Answer:

Explanation:

Here,  distance (s) = 220 m

initial velocity (u) = 0 m/s

acceleration due to gravity(since the ball is in free fall) = 9.8 m/s

to find : final velocity (v)

Formula : v^2 = u^2 + 2as

Therefore

v^2 = 0 + 2 x 9.8 x 220

v^2 = 4312

v = 65.66 m/s
