	A body freely falling from the rest has a velocity ‘v’ after it falls through a height ‘h’. The distance it has to fall down for its velocity to become double, is
	The time taken by a block of wood (initially at rest) to slide down a smooth inclined plane 9.8 m long (angle of inclination is \[{30^o}\]) is
	Velocity of a body on reaching the point from which it was projected upwards, is
	A body projected vertically upwards with a velocity \[u\] returns to the starting point in 4 seconds. If \[g = 10\]m/sec2, the value of \[u\] is
	Time taken by an object falling from rest to cover the height of \[{h_1}\] and \[{h_2}\] is respectively \[{t_1}\] and \[{t_2}\] then the ratio of \[{t_1}\] to \[{t_2}\] is
	A body is thrown vertically up from the ground. It reaches a maximum height of 100m in 5sec. After what time it will reach the ground from the maximum height position
	A body thrown vertically upwards with an initial velocity \[u\] reaches maximum height in 6 seconds. The ratio of the distances travelled by the body in the first second and the seventh second is
	A particle is thrown vertically upwards. If its velocity at half of the maximum height is 10 m/s, then maximum height attained by it is (Take \[g = 10\] m/s2)
	A body, thrown upwards with some velocity, reaches the maximum height of 20m. Another body with double the mass thrown up, with double initial velocity will reach a maximum height of
	A balloon starts rising from the ground with an acceleration of 1.25 m/s2 after 8s, a stone is released from the balloon. The stone will (\[g = 10\] m/s2)
