Question

Raindrops fall vertically at 4.5 m/s relative to the earth. What does an observer in a car moving at 22.0 m/s in a straight line measure as the velocity of the raindrops?

a) 17.5 m/s
b) 26.5 m/s
c) 18.5 m/s
d) 27.5 m/s

Answer 1

The velocity of the raindrops as measured by the observer in the car is 26.5 m/s.

Step-by-step explanation:

The velocity of an object moving in a straight line can be calculated by adding the velocities of the object and the observer. In this case, if the raindrops are falling vertically at 4.5 m/s relative to the earth, and the observer is in a car moving at 22.0 m/s, the velocity of the raindrops as measured by the observer in the car is the sum of these velocities, which is 26.5 m/s.
