# 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?

(A)
