A body is projected with velocity m/s with an angle of projection 60 with horizontal. Calculate velocity on that point where body makes an angle 30 with the horizontal.
(1) 20 m/s
(4) 10 m/s
A body thrown vertically so as to reach its maximum height in t second. The toal time from the time of projection to reach a point at half of its maximum height while returning (in second) is:
A projectile is given an initial velocity of . The cartesian equation of its path is (g = 10 )
A body is thrown horizontally with a velocity from the top of a tower of height h. It strikes the level ground through the foot of the tower at a distance x from the tower. The value of x is:
The gravity in space is given by . Two particles are simultaneously projected with velocity and . Then, the ratio of their times of flight
