When a body is projected vertically upwards, the direction of acceleration is:
Upwards
Downwards
Both (1) & (2)
Neither (1) nor (2)
Maximum height (h) reached by a body thrown vertically upwards with velocity (u) is given by:
h = u²/2g
h = u/2g
h = 2g/u²
h = 2u²/g
Maximum height attained by a body is directly proportional to:
Initial velocity
Square of initial velocity
Cube of initial velocity
Square root of initial velocity
The time of ascent is given by the formula:
t = u/g
t = g/u
t = 2u/g
t = 3u/g
If 'h' is the maximum height of the tower, then time taken by the body to reach the ground from the top is:
t = 2u/g
t = √(2h/g)
t = 2g/h
t = g/2u
Time of flight is given by the formula:
t = u/g
t = 2u/g
t = g/u
t = 3u/g
A stone is thrown vertically upwards with velocity 19.6 m/s. Time of ascent is (g = 9.8 m/s²):
1 s
2 s
3 s
4 s
A stone is projected vertically upwards with velocity 30 m/s. Maximum height reached is (g = 10 m/s²):
30 m
35 m
40 m
45 m
A ball is thrown up and attains a maximum height of 100 m. Its initial speed is (g = 10 m/s²):
20 m/s
25 m/s
30 m/s
40 m/s
A stone is projected vertically upwards with velocity 20 m/s. Total time in air is (g = 10 m/s²):
2 s
3 s
4 s
8 s
A body projected vertically upwards with velocity 20 m/s. Maximum height reached by the body is (g = 10 m/s²):
30 m
40 m
20 m
10 m
Velocity with which a body has to be thrown to reach maximum height h is:
√(2gh)
√(h/2g)
√(gh)
√(3gh)
