I am having trouble with some of this question.

'A student standing at the top of a cliff shoots an arrow from a height of 30.0 m at 25.0 m/s and an initial angle of 32.0 degrees above the horizontal.

b. How high above the landscape under the cliff with arrow rise? assume a level landscape

c. How far off course will the arrow be after 3.35 s if there is a 12.0 m/s crosswind (A crosswind is 90 degrees to the original motion, asssume the arrow goes to the side at the speed of the crosswind.)

d. What will be the speed and angle of the arrow 3.35 s after release if there is no crosswind

*neglect friction nd air resistance*'
