A rugby player passes the ball 9.75 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? (Answer in Degrees) What other angle gives the same range? (Answer in Degrees) For the pass using the smaller of the two angles, how long is the ball in the air? (answer in Seconds)

A golf ball struck on earth rises to a maximum height of 60 m and hits the ground 230 m away. How high will the same golf ball travel on the moon if the magnitude and direction of its velocity are the same as they were on earth immediately after the ball was hit? Assume that the ball is hit and lands at the same elevation in both cases and that the effect of the atmosphere on the earth is neglected, so that the trajectory in both cases is a parabola. The acceleration of gravity on the moon is 0.165 times that on earth.
A ball is thrown from the ground with an initial velocity of 20 m/s at an angle of 30 degrees above the horizontal. Ignoring air resistance, calculate the maximum height reached by the ball and the horizontal distance it travels before hitting the ground. Assume the acceleration due to gravity, g, is 9.8 m/s² and take the direction of upward motion as positive.
