Question

a stone is released from top of the tower of height 970m. Calcuate the velocity after 3 secs.​

Answer 1

using the formula

v = u + a x t

We get

u = 0, as it is released, so there is no initial velocity

a = gravity, which is 10 m/s

and time is 3 sec

v = (0) + 10 x 3

v = 30m/s

hope it helped
