Question

momentum of any body change from 200 km per second square to 120 kilometre per second square is 10 second what is the force exert on body ​

Answer 1

Answer:

Explanation:

Given,

Initial Momentum = 200 km/s

Final Momentum = 120 km/s

Time (t) = 10 s

Change in momentum = (120-200) km/s

= -80 km/s

Force = Δp/Δt

= (-80/10) N

= -8 N

(Negative Force means that the pace of the object has slowed down as the force is applied on the opposite direction of the object moving)

Hope this helps.
