A ball is thrown from the ground at an angle of 6 to the ground, with initial speed 10. The gravitational acceleration is given by gj. You can write your answers in terms of g, and assume there is no friction.

(a) (2 points) What is the initial velocity of the ball?

(b) (4 points) Find v(t), the velocity of the ball at time t.

(c) (4 points) Find t > 0 when the ball hits the ground.
