Question

a body having mass 50 kg change its velocity 54 kilometre per hour to 72 kilometre per hour in 10 seconds find the force applied ,acceleration, change in momentum

Answer 1

Mass of car m = 1500 kg. Initial velocity = 54 km/h = 54 x 5/18 = 15 m/s. Final velocity = 72 km/h = 72 x 5/18 = 20 m/s
