Question

1. The Earth is moving around the Sun along an orbit that is approximately circular.

The radius of the orbit is 150 million kilometers. The Earth can complete a full

circle in approximately 365.25 days (that is, one year). Within half a year, what is

(a) the average velocity and (b) the average speed of the Earth relative to the Sun?

Express your answers in kilometers per second, km/s. (Hint: draw a diagram of the

orbit.)

2. Spider-Man jumped off a building that is 112 meters tall with zero initial vertical

velocity. If he fell without the aid of air resistance and his superpower (which is

NOT the actual case), (a) how much time would it take before he hit the ground?

(b) How much distance would he have moved in the last one second of the fall?
