# If raindrops are falling vertically at 7.50 m/s, what angle from the vertical do they make for a person jogging at 2.25 m/s?

To determine
The angle from the vertical the raindrops makes for the jogging person.

Explanation

The velocities are related as the equation

vRP=vREâˆ’vPE

Here,

vRP is the velocity of the rain relative to the person

vRE is the velocity of the rain relative to the Earth

vPE is the velocity of the person relative to the Earth

The vector diagram of the velocities is given as,

From the vector diagram,

tanÎ¸=vPEvRE

Substitute 2
