1.How far does a car travel in 0.75 h, if it is moving at a constant speed of 88km/h? Then calculate the velocity if the start point is equal to the endpoint.

2.A passenger elevator travels from the first floor to the 60th floor, a distance of 210 m in 35s.
What is the elevator’s speed?
What is the elevator’s velocity?

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
