OK, ive been trying to get problems like these where you are given the angle (but not the velocity) of the direction in which a projectile is fired. I have tried as many ways as i could conceive using kinematics, but i keep getting stuck. If anyone could just give me an idea how to go about getting a little more info so i can complete the problem, it would be greatly appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

Barry Bonds hits a home run so that the baseball just clears the top row of bleachers, 23.6 m high, located 130 m from the home plate. The ball is hit at an angle of 42° to the horizontal, and air resistance is negligible. Assume that the ball is hit at a height of 1.00 m above the ground. Find the following values.

(a) the initial speed of the ball

(m/s)

(b) the time at which the ball reaches the cheap seats

(s)

(c) the velocity of the ball when it passes over the top row

(____i+____j m/s)

(d)the speed of the ball when it passes over the top row

(m/s)
