A football is kicked from the ground at 27 m/s at an angle of 42 degrees above the horizontal (ground). No one gets in the way until after it hits the ground. Use the value g=9.8 m/s^2. Assuming that the ground is level and that there is negligible air resistance, wind, etc.

a) How much time after the ball is kicked does it first hit the ground?

b) How far away from the kick does the ball land?

c) To what maximum height does the ball go?

d) What is the displacement of the ball (distance and direction) 1.0 s after the ball is kicked?

e) What is the velocity of the ball (speed and direction) 1.0 s after the ball is kicked?

Please help me by showing me steps, etc. I do not really know where to start, what equations to use, etc. for some of the problems. Thanks!
