Question

Problem 3:
You are on top of a cliff, which is 150 m above a flat ground below. You throw a ball at a
velocity of 8.40 m/s and at an angle of 20° above the horizontal.
1. How long does it take to reach the ground?
2. How far is it from the base of the cliff to the point of impact? (Range)

Answer 2

Answer:

Time of Flight. okay

150 = 8.4 sin 20 -5 t^2

X : u cos 20 X T

solve for t from above.
