Question

II. Multi Correct Choice Type: 18.1f a body is dropped from a tower of height 50m, then [ g=10 m/s2) 1) The time it takes to reach the ground is 10 sec. 2) The time it takes to reach half the length of the tower is 5 sec 3) The velocity with it strikes the ground is 1000 m/s. 4) The velocity of the body at half of the maximum height is 500 m/sec​

Answer 1

Explanation:

s=ut+0.5at 2

180=0+0.5(10)t2

t=6s

v=u+at=0+10(6)

=60m/s
