Density: Elasticity. Life saver!

A 60-kg motor sits on four cylindrical rubber blocks. Each cylinder has a height of 3.0 m and a cross-section area of 15 cm^2. The shear modulus for this rubber is 2.0MPa. (a) If a sideway 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 ifdisturbed?
