Time taken by a freely falling body to touch the ground is called
Time of flight
Time of descent
Time of ascent
Time period
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
A ball which is at rest is dropped from a height h metre. As it bounces off the floor its speed is 80% of what is just before touching the ground. The ball will then rise to nearly a height
0.94 h
0.80 h
0.75 h
0.64 h
A bomb is dropped from an aeroplane flying horizontally with a velocity 469 m/s at an altitude of 980m. The bomb will hit the ground after a time.
2s
√2 s
5 √2 s
10 √2 s
The time of ascent is directly proportional to
initial velocity
final velocity
acceleration due to gravity
time of flight
What is the final velocity of a body, which is fell down from a height of 5m?
40m/s
30m/s
20m/s
10m/s
A car accelerates uniformly from rest to a speed of 5 m/s over a distance of 30 m. Determine the acceleration of the car.
0.365m/s2
0.416m/s2
0.26m/s2
0.23m/s2
A stone released with zero velocity from the top of tower reaches the ground in 4s. The height of the tower is about
