A cyclist is travelling down a hill at a speed of 9.2ms-1. The hillside makes an angle of 6.3° with the horizontal. Calculate for the cyclist, the vertical speed and horizontal speed.

The slope of a velocity time graph over any interval of time gives the during that interval

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
