Answer to Question #335684 in Physics for nad

Question

A bus is moving at 5.0 m/s when a passenger walks forward at 1.5 m/s relative to the bus. How fast is this passenger moving as seen and measured by (a) a person waiting at the bus stop and (b) the driver of the bus?

Answer 1

Given:

$v_b=5.0\:\rm m/s$

$v_p=1.5\:\rm m/s$

(a)

$$V_r=v_p=1.5\:\rm m/s$$

(b)

$$V_r=v_b+v_p=5.0+1.5=6.5\:\rm m/s$$
