A ball is thrown downwards at 15 degree to and below the horizontal with a velocity of 15m/s from a slope of 10m high. Determine the time taken by the ball to travel in the air and the horrizontal distance it will travel

Answer 1

Solve this equation for the travel time, t:

Y (vertical distance fallen)
= 15 sin15*t + (g/2) t^2 = 10

where g = 9.8 m/s^2

Then multiply the positive root by the horizontal component, 15 cos 15
