Arock is rolling down a hill. at position 1, its velocity is 2.0 m/s. twelve seconds later, as it passes position 2, its velocity is 44.0 m/s. what is the acceleration of the rock?

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.
