A60-kg motor sits on four cylindrical rubber blocks. each cylinder has a height of 3 cm and a cross-sectional area of 15 cm2. the shear modulus for this rubber is 2.0 mpa. a.) if a sideways force of 300 n is applied to the motor, how far will it move sideways? b.) with what frequency will the motor vibrate back and forth sideways if disturbed?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
