Question

A scooter of mass 120 kg is moving with a uniform velocity of 108 km/lu. The magnitude of force required to stop the vehicle in 10 sec is (40 k) Newton, then find the value of k.​

Answer 1

Answer:

360N

Explanation:

mass of the object =120kg

initial velocity of the object = 108km/hr (30m/s)

final velocity of the object = 0m/s

given time =10sec.

Therefore force,

force = change in momentum/time taken

F= (mv-mu)/t

F= (120*0-120*30)/10

F= (0-3600)/10

F=-3600/10

F= -360N

therefore the answer in magnitude is 360N
