A stone falls from a balloon that is descending at a uniform rate of 12m/s. The displacement of the stone from the point of release after 10 sec is
A body A is projected upwards with a velocity of 98m/s. The second body B is projected upwards with the same initial velocity but after 4 sec. Both the bodies will meet after
A body falls freely from rest. It covers as much distance in the last second of its motion as covered in the first three seconds. The body has fallen for a time of
A stone is dropped into water from a bridge 44.1m above the water. Another stone is thrown vertically downward 1 sec later. Both strike the water simultaneously. What was the initial speed of the second stone
An iron ball and a wooden ball of the same radius are released from the same height in vacuum. They take the same time to reach the ground. The reason for this is
A body is thrown vertically upwards. If air resistance is to be taken into account, then the time during which the body rises is
A ball P is dropped vertically and another ball Q is thrown horizontally with the same velocities from the same height and at the same time. If air resistance is neglected, then
A body is released from a great height and falls freely towards the earth. Another body is released from the same height exactly one second later. The separation between the two bodies, two seconds after the release of the second body is
An object is projected upwards with a velocity of 100 m/s. It will strike the ground after (approximately)
A body is released from the top of a tower of height h . It takes v=1/2bt²+v_0sec to reach the ground. Where will be the ball after time t/2 sec
A body falls from rest, its velocity at the end of first second is (g=32ft/sec)
A stone thrown upward with a speed u from the top of the tower reaches the ground with a velocity 3u. The height of the tower is
Two stones of different masses are dropped simultaneously from the top of a building
A body thrown with an initial speed of 96ft/sec reaches the ground after (g=32ft/sec²)
A stone is dropped from a certain height which can reach the ground in 5 second. If the stone is stopped after 3 second of its fall and then allowed to fall again, then the time taken by the stone to reach the ground for the remaining distance is
A particle is dropped under gravity from rest from a height h(g=9.8m/sec²) and it travels a distance 9h/25 in the last second, the height h is
A balloon is at a height of 81 m and is ascending upwards with a velocity of 12 m/s. A body of 2kg weight is dropped from it. If g=10m/s² , the body will reach the surface of the earth in
Water drops fall at regular intervals from a tap which is 5m above the ground. The third drop is leaving the tap at the instant the first drop touches the ground. How far above the ground is the second drop at that instant
A ball is thrown vertically upwards from the top of a tower at 4.9ms¯¹ . It strikes the pond near the base of the tower after 3 seconds. The height of the tower is
A rocket is fired upward from the earth's surface such that it creates an acceleration of 19.6 m/sec2. If after 5 sec its engine is switched off, the maximum height of the rocket from earth's surface would be
A bullet is fired with a speed of 1000m/s in order to hit a target 100 m away. If g=10m/s², the gun should be aimed
A body starts to fall freely under gravity. The distances covered by it in first, second and third second are in ratio
P,Q and R are three balloons ascending with velocities U,4U and 8U respectively. If stones of the same mass be dropped from each, when they are at the same height, then
A body is projected up with a speed 'u' and the time taken by it is T to reach the maximum height H. Pick out the correct statement
A body falling for 2 seconds covers a distance S equal to that covered in next second. Taking g=10m/s² ,S=
