Question

question 1 of 25 a man walks forward on a bus. to a stationary observer, the bus moves east at a speed of 18 m/s. if the man moves 1.5 m/s east relative to the bus, what is his velocity in the frame of reference of a stationary observer? a. 16.5 m/s east b. 16.5 m/s west c. 19.5 m/s east d. 18 m/s east

Explanation:

Step1: Determine velocities

Bus velocity: \( v_{bus} = 18 \, \text{m/s east} \); Man relative to bus: \( v_{man/bus} = 1.5 \, \text{m/s east} \)

Step2: Add velocities

\( v_{man/observer} = v_{bus} + v_{man/bus} = 18 + 1.5 = 19.5 \, \text{m/s east} \)

Answer:

C. 19.5 m/s east
