Question

a body is projected vertically up reaches the maximum height in 5 seconds find (a) initial velocity,(b) maximum height,(c) Time of flight​

Answer 1

Answer:

A body is thrown vertically upwards and takes 5 seconds to reach maximum height. The distance travelled by the body will be same in :

g = 10 m/sec^2 V0 = g × t = 70 × 5 = 50 m/s from t = 0 to t = 1 sec h = (V0 × 1 - 5 × 10^2) - 0 = 50 - 5 = 45 m up from t = q to t = 10 sec h = [V0 ...

Answer 2

b. Maximum height

hope it helps you
