A 89.0 N grocery cart is pushed 13.0 m along an aisle by a shopper who exerts a constant horizontal force of 40.0 N. If all frictional forces are neglected and the cart starts from rest, what is the grocery cart's final speed?

Answer 1

net force=mass*acceleration
40-friction= mass* a

find a.
then,

vf^2=2a*distance

Answer 2

8.94
