Question

a body of mass 5kg moves with an acceleration of 4 m/s calculate it's change in momentum in 3seconds​

Answer 1

Answer:

first of all acceleration isn't m/s.

Explanation:

Here,

a = 4 , t is 3 secs and mass is 5kg.

the change in velocity is....

$dv = (4)(3) = 12$

the change in momentum is = mass times change in velocity

$d(momentum) = 5(12) = 60$

I am done .

Answer 2

a = 4 , t is 3 secs and mass is 5kg.

To find :- the change in velocity

formula :-     p = m*v

solution :- p = m*v

                     = 5*12

                     = 60 kg m/s
