A body is projected horizontally with velocity 196 ms-1 from height 400m. What is the time to reach the ground?
5s
9s
15s
20s
The time taken by a body, which is falling down to reach the surface of earth is known as
Time of ascent
Time of descent
Time of fall
Time of lifting
A stone released with zero velocity from the top of tower reaches the ground in 4s. The height of the tower is about
20m
40m
80m
160m
The time of ascent is directly proportional to
initial velocity
final velocity
acceleration due to gravity
time of flight
A particle is thrown vertically upwards. Its velocity at half of the height is 10 ms-1. Then the maximum height attained by it is (Take g= 10ms-2).
16m
10m
8m
18 m
