Answer 2

Answer:

The horizontal floor has a frictional force F that inhibits the movement of the cart.

Acceleration of cart=P−F=0 as th e cart moves with constant velocity and acceleration is 0

So, F=P

When a force of 1.2P acts fon the cart, acceleration a of the cart is

1.2P−F=ma

1.2P−P=20kg×0.05m/sec

2

P=1/0.2=5N
