When the shuttle bus comes to a sudden stop to avoid hitting a dog, it decelerates
uniformly at 3.5 m/s2 as it slows from 8.8 m/s
to 0 m/s.
Find the time interval of acceleration for
the bus.
Answer in units of s.

The metric unit of electrical power is the watt volt ampere ohm

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.
