Three identical balls are thrown from the top of a building all with the same initial speed. The first is thrown horizontally, the second at some angle above the horizontal, and the third at some angle below the horizontal, as shown below. Neglecting air resistance, rank the speeds of the balls afrom fastest to slowest. (a) 1,2,3 (b)2,1,3 (c) 3,1,2 (d) all the three ball strike the ground at the same speed.
For all questions, assume concepts such as friction or air resistance are negligible,
unless stated otherwise in the question.
A ball is launched from ground level at an angle of 60˚ and with a speed of 15 m/s.
a)What is the maximum height the ball will reach?
b)How far horizontally will the ball travel before returning to ground level?
In the figure, you throw a ball toward a wall at speed 23.0 m/s and at angle θ0 = 36.0˚ above the horizontal. The wall is distance d = 21.0 m from the release point of the ball. (a) How far above the release point does the ball hit the wall? What are the (b) horizontal and (c) vertical components of its velocity as it hits the wall?
