A meterstick moving at 0.864c relative to the Earth's surface approaches an observer at rest with respect to the Earth's surface. (a) What is the meterstick's length as measured by the observer? m (b) Qualitatively, how would the answer to part (a) change if the observer started running toward the meterstick?

Using surgical tubing and ingenuity, you have constructed a water- balloon launcher in a window 22 m above the ground. Your device launches a water balloon at a speed of 19 m/s, and at an elevation of 0.25 radians above the horizontal. At what horizontal distance from the building will the water balloon strike the ground?

A plane is flying horizontally with speed 184 m/s at a height 2260 m above the ground, when a package is dropped from the plane. The acceleration of gravity is 9.8 m/s2 . What is the horizontal distance from the release point to the impact point? Answer in units of m. A second package is thrown downward from the plane with a vertical speed v1 = 69 m/s. What is the magnitude of the total velocity of the package at...
