A 75.0-kg cross-country skier is climbing a 3.00o slope at a constant speed of 2.00 m/s and encounters air resistance of 30.0 N. If he continues to exert at this power and to experience the same air resistance when he reaches a level area, what is his final velocity on level ground

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

Which of the following are appropriate acceleration units?

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
