The acceleration due to gravity on the planet A is 9 times the acceleration due to gravity on planet B. A man jumps to a height of 2 m on the surface of A. What is the height of jump by the same person on the planet B

If a body is thrown up with the velocity of 15 m/s then maximum height attained by the body is (g = 10 m/s²)

A packet is dropped from a balloon which is going upwards with the velocity 12 m/s, the velocity of the packet after 2 seconds will be

If a freely falling body travels in the last second a distance equal to the distance travelled by it in the first three second, the time of the travel is

The effective acceleration of a body, when thrown upwards with acceleration a will be

A ball is dropped from a high rise platform at t = 0 starting from rest. After 6 seconds another ball is thrown downwards from the same platform with a speed v. The two balls meet at t = 18s. What is the value of v. (take g = 10 m/s²)

A ball is thrown up under gravity (g = 10 m/sec²). Find its velocity after 1.0 sec at a height of 10 m

Two stones of equal masses are dropped from a rooftop of height h one after another. Their separation distanceagainst time will

At t = 0, a stone of mass 10 gm is thrown straight up from the ground level with a speed 10 m/s. After 1 s, a second stone of the same mass is thrown from the same position with a speed 20 m/s. What is the position of the first stone from the ground level at the moment?(Take g = 10 m/s²)

The ratios of the distances traversed, in successive intervals of time by a body, falling from rest, are
