We did a practical in which we bounced a ball from the same point onto an inclined ramp, from 10-50 degrees and measured the distance from where the ball was dropped and when it hit the table (i.e. place where it landed after it bounced off the ramp). I got these results:
(Note: I can only remember from 15-40 degrees, the distance travelled are estimates, as I can’t fully remember, but the trend is the same to what actually happened)
θ (angle of ramp to horizontal) (°) Distance travelled (cm)
2. Relevant equations
3. The attempt at a solution
So now I need to explain the results, I was thinking that it is due to the component of the velocity, so Vcosθ, changes from 25-40, in such a way that cosθ decreases, therefore the horizontal range of the ball decreases. However I then found that cosθ from 15-40 all decreases, so surely the horizontal range of the ball should decrease. So, I am confused, is my thinking correct or am I missing something? (Maybe V, the speed when the ball hits the ramp is different when the ramp is inclined at different angles?).
Any help is appreciated! Thanks!
