Answer:
Acceleration of the cart will be
Explanation:
We have given force F = 40 N
Mass of the cart = 20 kg
From newton's second law we know that force, mass and acceleration are related to each other
From second law of motion force on any object moving with acceleration a is given by
F = ma, here m is mass and a is acceleration
So
