The average cheetah in this town cheetah race runs 16 miles per hour. But, another cheetah won the race because it ran 20 miles per hour. If it can run at this constant spped for 5 and a 1/2 hours, how much will it run?

The necleus of an atom is made up of what subatomic particles?

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".

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
