3.1 What is the input gear? [2]

1.1 The word isometric means… [1]

3.5 Calculate the gear ratio of this gear system. [2]

2.5 Pascal’s principle proves that the pressure throughout a closed system is constant. [1]

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 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 [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?
