Suppose an oxygen molecule traveling at a velocity of 480m/s bounces back and forth between opposite sides of a cubical vessel 0.19 on a side. What is the average force the molecule exerts on one of the walls of the container? (Assume that the molecule's velocity is perpendicular to the two sides that it strikes.)
What is the average force per unit area?
At a time t = 3.40s , a point on the rim of a wheel with a radius of 0.210m has a tangential speed of 53.0m/s as the wheel slows down with a tangential acceleration of constant magnitude 11.0m/s2. Calculate the wheel's constant angular accelerat..
