Ok basically I've tried loads of methods of working it out and I'd just like to see how someone else would do it because all the answers I get don't seem right and I am not confident about them. A bit of explaining of why things that may seem odd are wouldn't be minded elther.
I've tried working out the speeds on both planes using 15Sin(30 and 15cos(30 but when I try and apply the answer to my motion equations S = ut + (0.5)(A)(t squared) and V(Squared) = U(Squared) + 2as, It doesn't seem to work out elther way. The way I did it in the end was using V = u + at working out U with sin and assuming a = -9.81 and V = 0.
Here's the question:
A ball is thrown from the ground with a velocity of 15ms at an angle of 30 to the horiziontal.
Calculate
A . It's time of flight(The time between the point at which it leaves the thrower's hand when it hits the ground) assuming that the ground is level.
B. It's range.
C. It's maximum height.
-Shoot.
