Q17 of 35 Page 143

Akash starting from rest acquire a velocity of 20 m per second in 6 second. If the mass of the car is 1200 kilogram. Calculator force.

Initial velocity = u = 0m/s

Final velocity = v = 20m/s


Time = t = 6s


Mass = m = 1200kg



=


= 20/6 m/s2


Force = Mass × Acceleration


= 1200kg × 20/62


= 4000N
