Question

Dr. C. #1: Exploding Projectile: A projectile of mass 9.6 kg is shot from the ground with an initial velocity of 12.4 m/s at an angle of 54° above the horizontal. A. Assuming the ground underneath the projectile's path is flat, what is the maximum height h the projectile reaches, its horizontal range R, and the time it spends in the air? Suppose that, at the peak of the projectile's motion, an explosion splits the projectile in half and one piece falls straight down. When (relative to the launch) and where (relative to the launch position) does that piece land? When and where does the other piece land? B. C. D. Instead of exploding at the peak and splitting the projectile in half, the explosion produces one piece of mass 6.5 kg that is observed 1.42 s after the launch at a height of 5.9 m and a horizontal distance of 13.6 m from the launch point. Find the location of the second fragment at that same time. Has it hit the ground yet?
