A stone attains a momentum of 1 kg m/s when it flies with a velocity of 2 m/s, then what will be the mass of the stone?
A stone is thrown in a vertically upward direction with a velocity of 5 m s−1. If the acceleration of the stone during its motion is 10 m s−2 in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?
