Agolfer hits a shot to a green that is elevated 3 m above the point where the ball is struck. the ball leaves the club at a speed of 16.6 m/s at an angle of 40.9° above the horizontal. it rises to its maximum height and then falls down to the green. ignoring air resistance, find the speed of the ball just before it lands.

14.72 m/s

Explanation:

Given

Initial velocity (u)=16.6 m/s

Horizontal velocity component ()=16.6cos40.9=12.54 m/s

As the ball comes down so its vertical displacement is zero except 3 m elevation

Thus

there will be no change is horizontal velocity as there is no acceleration

Therefore Final Velocity

v=14.72 m/s

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.
