Aslot car moves at 1.50 m/s on its curved track of radius 36.0 sum. it's motor keeps it moving at a constant speed. what is its centripetal acceleration? if it has a mass of 0.140 kg, what force does it need to keep it on the circular path?

Acar drives toward the right over the top of a hill, as shown below. which arrow represents the centripetal acceleration? w x y z

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
