- Homework Statement
- Find the height of a cliff using a ball thrown at an angle and find how long it takes the ball to hit the ground.
- Relevant Equations
- a-sinA, aCosA
This is the question:
A ball is thrown with a speed of 6m/s at an angle of 25° above the horizontal from the top of a cliff. The ball strikes the ground 15 m from the bottom of the cliff.
How long does it take the ball to strike the ground?
How long is the cliff?Here's a visual representation of the problem.
I broke the angle into vectors
I solved for the time of the ball in the
x-axis
t=d/v
t=15m / 5.4378m/s
t = 2.7584 Seconds
But now I'm stuck and I'm lost on what to do next
