Question

mass is 200 kg velocity attained by the automobile in 3 second is 12 metre per second find the force​

Answer 1

Answer:

Answer 2

Answer:

The answer is 800 N

Explanation:

mass = m = 200kg

velocity after 3 seconds = Vf = 12m/s

=> acceleration = Vf - Vi / t

(if the mass is at rest first then the initial velocity would probably = 0)

=> acceleration = 12-0/3 = 12/3 = 4m/s2

Thus the force = m×a = 200 × 4 = 800 N
