Object 1, m1 = 3kg, collides and permanently sticks together with a stationary second object, m2 = 2kg. After the collision, they bounce off a moving third object, m3 = 2kg. v1,i = +3m/s, v3,i = -2m/s, and object 3 bounces off at twice the speed it comes in. Note that m1 and m2 are still stuck together. What are the final velocities of m1 and m2?
A projectile is fired from the origin (at y = 0 m) as shown in the figure. The initial velocity components are = 920 and = 79 . The projectile reaches maximum height at point P, then it falls and strikes the ground at point Q. In the figure, the y-co..
