Jake the deliveryman pushes a box up a ramp, exerting a force of 350 N. He walks on the
ramp, pushing the box for 25.0 m. If the box
has a mass of 50.0 kg, what is the height of
the ramp and the angle it makes with the
horizontal? Ignore friction.

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
