Q. A 96N grocery cart is pushed 10m along an aisle by a shopper who exerts a constant horizontal force of 40-N. If all frictional forces are neglected and cart starts from rest, what is the grocery cart's final speed?

Q. A curve of radius 120 m is banked at an angle of 25o. If the coefficient of static friction between road and car is 0.4, what are the maximum and minimum speeds the car can have without skidding?
