object m1=1.45kg starts at an initial height h1i=0.350m and speed v1i= 4.00 m/s,swings downward and strikes (in an elastic collision) object m2=4.80 kg which is initially at rest. Determine the following.

(a) speed ofm1 just before the collision.

m/s

(b) velocity (magnitude and direction) of each ball just after the collision (Assume the positive direction is toward the right. Indicate the direction with the sign of your answer.)

m/s (m1)

m/s (m2)

(c) height to which each ball swings after the collision (ignoring air resistance)

m (m1)

m (m2)
