a small ball of mass 5 kg is l.
a small ball of mass 5 kg is launched upward with an initial speed of 10m/s, from the ground, at an angle of 60 above the horizontal, as shown. The ball lands on a slope that makes an angle of 30 with the horizontal. The distance along the slope that the ball land is 2m.
(i) how long after the ball is launched does it hit the slope?
(ii) what is the distance, d, that the bottom of the slope is away from the point where the ball is launched?
(iii) with what speed does the ball hit the slope?
(iv)Write symbolic equation for the trajectory of the ball. Sketch a graph of this equation, numerically labelling the position (x- and y- coordinates) where the ball reaches its maximum height and where it hits the slope.
