Aforce f acts in the forward direction on a cart of mass m. a friction force/opposes this motion. (a) use newton’s second law and show that the acceleration of the cart is (f−f)/m. (b) if the cart’s mass is 4.0 kg, the applied force is 12.0 n, and the friction force is 6.0 n, show that the cart’s acceleration is 1.5 m/s2.

Explanation:

It is given that cart is accelerating therefore a net force is acting on the cart which is accelerating it.

If F is the applied force and f is the friction force then acceleration is given by

(ii)If

mass

acceleration

acceleration is given by

hèllo, sorry i really need some more points so if you need this qustion answered than retype it
