A golfer hits an approach shot with a velocity of 38.2 m/s at 50 degrees above the horizontal. The golf ball lands directly next to the hole, 5.50 m above the ball’s original position, and stops immediately.
What was the TOTAL final velocity of the golf ball directly before it hit the ground?
In the X-direction,
The ball’s velocity can be represented as,
Here, v, u, a, and t represent the ball’s final velocity, the ball’s initial velocity, the ball’s acceleration, and the time, respectively.
The ball experiences no force in the X-direction; thus, its acceleration is zero.
The ball’s initial velocity in the X-direction can be represented as,
Here, θ is the angle at which the ball is shot.
Thus,
Substitute the relevant values.
