Q. A jet plane is flying at a constant altitude. At time it has components of velocity 85 , 109 . At time 30.0 the components are 173 , 41 .Find the magnitude of the average acceleration.
Q. A ball is launched up a ramp such that it takes 2.0 seconds for it to travel 3.0 m up the incline before rolling back down. Sketch the graphs of position, velocity, and acceleration along the ramp as functions of time. Be sure to label the graphs with units and values to indicate any critical points of the ball's motion.
