Question

A force of 5 Newton is applied on a mass that accerlates at 2.5 cm/S a Find the mass of the body in case the force acts for 5 minutes b Find the speed of the body and the distance covered

Answer 1

given :

force applied = 5 N

acceleration = 2.5 cm /s ^2

convert 5N to dyne

force = 5 . 10 ^5 dyne

as we know

force = mass . acceleration

5.10^5 = mass . 2.5

mass = 5 . 10 ^5 / 2.5

mass = 5 . 10 . 100000 / 25

mass = 200000 gram ( in cgs system )

mass = 200 kg
