Question

please tell me who are intelligent in math please answer this


A 55 kg car accelerates from 4.2 m/s to 7.8 m/s in 15 s by applying a constant force. What change in momentum occurs? How large of a force is exerted​

Answer 1

Answer:

sol. we know, force = change in momentum/ change in time

=> F = ∆p/∆t = m∆v/∆t = ( 7.8 - 4.2 ) / 15

= 3.6/15 = 0.24 N

I think this should be correct answer
