4-57. An astronaut
strikes a golf ball on the Moon where the magnitude of the acceleration
due to gravity is 1.6 m/s2. The ball takes off with a
velocity
of 32 m/s at an angle 35° 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 x
102 m (b) 24 s (c) 6.2 x 102 m]
The first thing
required is a good sketch of the physical situation. Which of the
following
best represents this problem?
