4) A boy throws a rock with an initial velocity of 2.15 m/s at 30.0° above the horizontal. If air resistance is negligible... a) how long does it take for the rock to reach the maximum height of its trajectory? b)How far from the boy does the rock land? c) What is the velocity of the rock just before it hits the ground? (0.110s, 0.408m, 2.15m/s @-30.0°)
