Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_58

2/58 A boy tosses a ball onto the roof of a house. For the launch conditions shown, determine the slant distance \( s \) to the point of impact. Also, determine the angle \( \theta \) which the velocity of the ball makes with the roof at the moment of impact. Given Launch Conditions: Initial speed \( v_0 = 12.5 \text{ m/s} \) Launch angle \( \alpha = 50^\circ \) Release height \( h_1 = 1.75 \text{ m} \) above the ground Horizontal distance to the wall \( d = 9 \text{ m} \) Height of the wall/eave \( h_2 = 4 \text{ m} \) Roof slope defined by a rise/run of \( 5/12 \)
