A car starts from rest and accelerates uniformly at a rate of 8.0 meter per second squared for 1.0 meters. At the end of this time interval, the car's final velocity is meters per second.

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.
