Two objects are moving downward at a speed of 3 cm/s. Object A has a mass of 2kg and Object B has a mass of 1kg. You want both objects to move to the left at a speed of 3cm/s. In what direction or (directions) should you exert the forces that will make the desired change?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
