Question

A body of mass 30kg has a momentum of 150kg m/s.find its velocity

Answer 1

Momentum is calculated as follows:

Momentum = mass(kg) x velocity(m/s)

Therefore velocity = momentum/mass
                           = 150kgm/s/30kg
                           =  5m/s

Hence the velocity =  5m/s

Answer 2

Answer:

The velocity of the body is 5 m/s.

Explanation:

Given the mass of the body, m= 30 kg.

The momentum of the body, p = 150 kg m/s.

We have to calculate the velocity of the body.

The momentum is given as,

p =m x v.

here, v is the velocity of the body.

substitute the given values, we get

$150kg.m/s=30kg\times v$

$v=\frac{150kg.m/s}{30kg}$

v = 5 m/s.

Thus, the velocity of the body is 5 m/s.
