A force of 15N is applied to a 5 kg ball causing it to roll across a slick horizontal surface with friction exerting 10N of force in opposition. The ball then rolls into a grassy area where the frictional force increases to 13N.
What is the net force of the ball? What is the acceleration of the ball.
Net force= 2N forward
Acceleration= 0.4m/s2
