Q. A golf ball is struck with a five iron on level ground. It lands 92.6 away 4.20 later. What was (a) the direction and (b) the magnitude of the initial velocity?
Q. At the surface of Jupiter's moon Io, the acceleration due to gravity is 1.81 m/s^2. A watermelon has a weight of 53.0 N at the surface of the earth. In this problem, use 9.81 m/s^2 for the acceleration due to gravity on earth.
