1) A golfer hits his approach shot at an angle of θ = 51.5°, giving the ball an initial speed of v0 = 38.3 m/s The ball lands on the elevated green, yf = 5.9 m above the initial position near the hole, and stops immediately. (a) How much time passed while the ball was in the air? (b) How far did the ball travel horizontally before landing? m (c) What was the peak height reached by the ball? m
1) A golfer hits his approach shot at an angle of
θ = 51.5°,
giving the ball an initial speed of
v0 = 38.3 m/s
The ball lands on the elevated green,
yf = 5.9 m
above the initial position near the hole, and stops immediately.
(a) How much time passed while the ball was in the air?
(b) How far did the ball travel horizontally before landing?
m
(c) What was the peak height reached by the ball?
m
2)A ball starts from rest at the left end of the track shown in the figure below. The ball flies off the right end of the track and follows the parabolic trajectory shown. Suppose the right end of the track is
1.2 m
above the floor and makes an angle of
35.0°
with the horizontal. Also suppose the ball leaves the track with a speed of
3.8 m/s.
Determine where the ball hits the floor.
