A small dense ball with mass 0.9 kg is thrown with initial velocity m/s at timet = 0 from a location we choose to call the origin ( 111). Air resistance is negligible. (a) When the ball reaches its maximum height, what is its velocity? m/s (b) When the ball reaches its maximum height, what is t? (c) At a later time the ball's height 3; has returned to zero, which means that the arithmetic average value of 1),, from t = 0 to this time is zero. At this instant, what is the time t? (d) At the time calculated in part (c), when the ball's height y returns to zero, what is a}? (This is called the range of the trajectory.) (e) What is the angle in degrees with respect to the positive xaxis of the velocity at the time calculated in part (c)? Present your answer as a positive value less than 360
