A shell is shot with an initial velocity vo of 47 m/s, at an angle of e, = 60° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass. One fragment,whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that the air drag is negligible?Explosion

The following figure shows 2 particles of masses m1 and m2, with velocities before the collision of magnitude v1 and v2. If the collision is perfectly elastic, find the magnitude of the velocities v1' and v2' after the collision and the angle of incidence θ, as a function of the masses and velocities before the collision.
A marksman fires a practice round from A toward a target B. If the target diameter is 180 mm and the target center is at the same altitude as the end of the rifle barrel, determine the range of "shallow" launch angles for which the round will strike the target. Neglect aerodynamic drag and assume that the round is directed along the vertical centerline of the target. (Note: The word "shallow" indicates a low-flying trajectory for the round.)

please answer in 20 minutes thank you! A 0.4 kg rubber ball has a horizontal velocity of 1.554 m/s at point A and goes through a projectile motion until it hits a smooth floor at point B. It then bounces off and reaches another peak in its trajectory at point C. The ball hits the smooth floor with an impact which has a coefficient of restitution of 0.8 in a very short span of time. Which of the following best approximates the speed of the ball just after it bounces off the floor for the first time? Which of the following best approximates the value of DISTANCE h?
