A firecracker in a coconut blows the coconut into three pieces. Two pieces of equal mass fly off south and west, perpendicular to each other. The third piece has twice the mass of the other two and is launched with speed [v] m/s at an angle of [theta] degrees north of east. After the explosion, what was the speed in m/s of the coconut piece launched toward the west?

A [m1] kg block is sliding along a frictionless surface. A second block with a mass of [m2] kg, sliding at a faster speed of [v2] m/s, collides with the first from behind and sticks to it. The final velocity of the combined blocks is [vf] m/s. What was the initial speed of the slower first block in m/s?

A [mw] kg block of wood sits on a frictionless table. A [mb] g bullet, fired horizontally, goes completely through the block, emerging at a speed of [vbf] m/s. You measure the speed of the block after the bullet exits and find it to be [vwf] m/s. What was the initial speed of the bullet in m/s?

A block is sliding along a frictionless surface at [v1] m/s. A second block with a mass of [m2] kg, sliding at a faster speed of [v2] m/s, collides with the first from behind and sticks to it. The final velocity of the combined blocks is [vf] m/s. What is the mass of the slower first block in kg?

A person uses a [F] N force to pull a child in a wagon up a hill. The combined mass of the child and wagon is [m] kg. The hill is [h] m high vertically and [d] m long along the slope. If the child and wagon are moving at [v] m/s at the top of the hill, how fast were they moving initially before climbing the hill?
