A ball is thrown from a height of 20 meters with an initial velocity of 10 m/s at an angle of 30° above the horizontal. Assume air resistance is negligible. (a) Find the x and y components of the ball's initial velocity. (b) What is the maximum height in meters reached by the ball? (c) For how many seconds is the ball in the air?
00:31:17 A person standing at the edge of a cliff throws a rock upward from a height of 400 ft above ground level with an initial velocity of 62 ft/s. What is the velocity of impact when the rock reaches the bottom of the cliff? Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to two decimal places. (Hint: Use h(1) = 1612 + 621 + 400 as the position function,...
