how long does it take to hit the ground?
20 + 27 sin50° t - 4.9t^2 = 0
Now use that t to find the speeds:
vertical speed 27 sin50° - 9.8t
horizontal speed: 27 cos50°
and the hor distance is just hor speed * time
A golf ball is shot from a tee, elevated 20m above the green, with an initial speed of 27m/s at an angle of 50° above horizontal.
a) What will be the speed of the golf ball before it hits the green, 20m below it started?
b) How much time will it take for the ball to travel from the tee, where it is shot to the green?
c) What horizontal distance will the ball travel in moving from the shot at the tee to hitting the green?
