Need help with physics problems please! Thank you!

5. A cheetah accelerates from rest up a 10 degrees slope at 6.2 m/s2.

a)Calculate the vertical distance that she rises in 3.2 s.

b)Calculate her final horizontal velocity.

6. A mountain biker rides horizontally off a 2.5 m high ledge and lands 6.0 m from the ledge. Calculate his initial speed.

7. A soccer player kicks a ball off the ground with a speed of 20 m/s at an upward angle of 30 degrees.

a)How much time does it take the ball to hit the ground?

b)How far away (in the x-direction) will it hit the ground?

8. A paperboy tosses a paper 15 m/s at an angle of 50 degrees above the horizontal. It lands on top of the roof 3.0 m above the paperboy.

a)Calculate the time the paper was in the air.

b)Calculate the horizontal distance between the boy and the paper. (Note: you will need the quadratic equation for this one. There will be two solutions for t, both positive. If you're not sure which one to use, it may help to draw a picture showing the arcing path of the newspaper and the height of the roof.)
