A firework of mass 1kg is shot in the air. At the highest point of its trajectory the firework has a velocity of 20m/s (horizontal) and explodes splitting into 2 parts, that fly off at 40° and 30° relative to the initial trajectory (see diagram). Part 1 that moves off at 40° has twice the magnitude of vertical velocity of part 2. Assume the total mass of the system doesn’t change, and neglect any other possible forces on the objects....

A ball of mass m is shot straight up into the air by a spring-loaded launcher. Initially, the spring is compressed by a distance D. After the spring is released, the ball has a velocity v out of the launcher and finally reaches a maximum height H. Ignoring air resistance, which of the following statements are true? True False If the spring constant is doubled, the ball will max out at height 8H True False The initial potential energy of the spring...
