When a horizontal force P acts on a cart of mass 20 kg,it moves with a uniform velocity on a hofloor.When a force of 1.2P acts on the cart,it moves with an acceleration of 0.5m/s^2.Find the value of P

1.2P = F , a = 0.5 m/s^2, m = 20 kg

F = ma, putting all values in equation, 1.2P = 20 * 0.5 = 10 SO, P = 10/ 1.2 P = 8.333 N
