Hi, this is my first post. My teacher gave us some very "hard" homework questions:
Alright: The first question concerns a car moving with acceleration [tex]5t^{2}[/tex] and initial velocity 4 m/s.
a) what is it's velicity at time t?
b) what is it's position at time t?
c) How far has it gone after time t=pi seconds.
2)
a) Assume I have a frictionless plane inclined at pi/2 radians and a box 6 ft up the plane, how long does it take to fall?
b) Assuming the rock took ten seconds to fall, how high did it start up?
