You arrive to science in 3 mins after your math class that is 900 meters away. How fast were you walking?

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.

When you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
