A projectile of mass 2.75 kg is fired in the air at an angle of 45.0∘45.0∘ to the horizon at a speed of 290.0 m/s. At the highest point in its flight, the projectile breaks into three parts of mass 2.00 kg, 0.70 kg, and 0.05 kg. The 2.00 kg part falls straight down after breakup with an initial speed of 10.0 m/s, the 0.70 kg part moves in the original forward direction, and the 0.05 kg part goes straight up. Find the speeds of the 0.7 and 0.05 kg pieces immediately after the break-up

Pick the correct answer

v0.7=11,300 m/sv0.7​=11,300m/s and v0.05=28.6 m/sv0.05​=28.6m/s

v0.7=586 m/sv0.7​=586m/s and v0.05=550 m/sv0.05​=550m/s

v0.7=1,140 m/sv0.7​=1,140m/s and v0.05=400 m/sv0.05​=400m/s

v0.7=806 m/sv0.7​=806m/s and v0.05=400 m/sv0.05​=400m/s

A 204-kg projectile, fired with a speed of 131 m/sat a 65.0 ∘  angle, breaks into three pieces of equal mass at the highest point of its arc (where its velocity is horizontal). Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally. A. Determine the magnitude of the velocity of the third fragment immediately after the explosion. B....

Two ice skaters, Daniel (mass 65.0 kg ) and Rebecca (mass 45.0 kg ), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 12.0 m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 8.00 m/s at an angle of 54.1 ∘ from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink.
