Question

A ball is thrown from the top of a tall building from point C as shown below The initial speed of the ball is vo and the initial launch angle is 8o Assume the acceleration due to gravity points downward towards the ground and has a constant magnitude of g. Neglect air resistance. For this assignment, do the following: 1. Create a reference frame and coordinate system you will use to solve this problem. 2. Find the time it takes (t*)for the ball to hit the ground in terms of (vo, 80, 9, h) 3. Find the distance L where the point of impact occurs in terms of (vo, 80, 9, h)

Please show all work using Kinetics and kinematics!

Thank you:)

thumbs up please

t = t_up + t_down Using Kinamatic equations: - t_up = v_if = u_i - g t_up v_0 sin theta_0/g = t_up - (i) because v^2_if = u^2_ii - 2 gh� h� = v^2_0 sin^2 theta_0/2 g t_down = squareroot (h + h�)/g = squareroot 2/g (h + v^2_0 sin^2 theta_0/2 g) t* = v_0 sin theta_0/g + squareroot 2/g (h + v^2_0 sin^2 theta_0/2 g) 3. L = v_0 cos theta_0 t* = v_0 cos theta_0 (v_0 sin theta_0/g + squareroot 2/g (h + v^2_0 sin^2 theta_0/2 g))
