Q1. A basketball star covers 2.6 m horizontally in a jump to dunk the ball. His motion through space can be modelled precisely as that of a particle at his center of mass. His center of mass is at elevation 1.02m when he leaves the floor. It reaches a maximum height of 1.80 m above the floor and is at elevation 0.900m when he touches down again.

Q2. A dog running in an open field has components of velocity = 3.10 and = -1.90 at time = 12.0. For the time interval from = 12.0 to = 23, the average acceleration of the dog has magnitude 0.44 and direction 34.3 measured from toward?
