Using a telescope, you track a rocket that was launched 13 km away recording the angle theta between the telescope and the ground at half‑second intervals. estimate the velocity of the rocket of theta(10)=0.205 and theta(10.5)=0.225.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
