Problem 4-57 Projectile

An astronaut strikes a golf ball on the Moon where the magnitude of the acceleration due to gravity is \(1.6\; m/s^2.\) The ball takes off with a velocity of \(32\; m/s\) at an angle \(35^\circ\) above the horizontal (the moon’s horizontal) and lands in a valley \(15\; m\) below the level where it started. Determine the golf ball's: (a) maximum height (b) time of flight (c) horizontal distance traveled.
[Ans. (a) \(1.1 \times 10^2\; m\)   (b) \(24\; s\)   (c) \(6.2 \times 10^2\; m\)]

The first thing required is a good sketch of the physical situation. Which of the following best represents this problem?
