A copper is 4 cm long at 10 Cº. The coefficient of linear expansion for copper is 1.7 x 10-5 (Cº)-1. Calculate the change in length (AL). when it is at 70 Cº.

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
