Experiment shows that the frictional drag force F of a car moving in air depends on the velocity V of it's motion, density P of the air through which it travels, and the cross-sectional area of the car. if the force is F = KP^x V^2y A ^z. Where x, y and z are the integers and k is a dimensionless constant, find the values of x, y and z.

Steelhead trout migrate up stream to spawn. occasionally they need to leap up small waterfalls to continue their journey. fortunately, steelhead are remarkable jumpers, capable of leaving the water at a speed of 8.0 m/s. a. what is the maximum height a steelhead trout can jump? b. leaving the water at 8.0 m/s, the trout lands on top of the water fall 1.8 m high. how long was it in the air?

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
