Question

An object possessing a kinetic energy of 275J and a linear momentum of 25m / s, so that the mass of the object is equal to:

Answer 1

Solution- Given data -

kinetic energy (K.E.) = 275 J

Linear momentum (p) = 25m / s

mass = ?

The linear momentum and the kinetic energy of a moving body are the body's properties which is very much related to velocity.

linear momentum (p) = m.v .......................(1)

Kinetic Energy (K.E.) = 1 / 2 m.v² ..............(2)

Hence,

{from equation (1)}

substitute all the numerical values, we get -

Which is required answer-

thank you-
