Question

A body of mass 40 kg is accelerating at a rate of 9 m/s2. What is the rate of change of linear momentum?​

Answer 1

Solution :-

Given that :

Mass of the body = 40 kg

Acceleration = 9 m/s²

Formula used :

Force = Mass × Acceleration

Let the rate of change of linear momentum be x.

According to the question,

=> Force = Mass × Acceleration

=> x = 40 × 9

=> x = 360

Hence,

The rate of change of linear momentum = 360 Newton.

Answer 2

$\bold {\huge {Your ~answer :-}}$

$\bf\huge\boxed{360\:N}$

--------------------------------------------------

Given —

Mass of body(m) = 40 kg

Rate of acceleration (a) = 9 m/s²

According to newton's second law of motion rate of change of linear momentum is directly proportional to the force applied.

$rate \: of \: change \: in \: momentum= \frac{change \: in \: momentum}{change \: in \: time}$

$= force = mass \times area$

F = 40 × 9 = 360 N

Therefore, Rate of change of Linear momentum is 360 N
