The weight of a body is 2.0 N. What is the mass of the body ? (g = 10 m s^-2)

The weight of a body on earth is 98 N where the acceleration due to gravity is 9.8 m s^-2. What will be it's (a) mass and (b) weight on moon where the acceleration due to gravity is 1.6 m s^-2 ?

What is the (a) force of gravity and (b) weight of a block of mass 10.5 kg? Take g = 10 m s^-2

A ball is released from a height and it reaches the ground in 3 s. If g = 9.8 m s^-2, find —

(a) the height from which the ball was released,

(b) the velocity with which the ball will strike the ground.
