Question

a westbound bus is traveling at a speed of 60 km/h with respect to a bus stop. at the same time, a car is traveling east at 60 km/h with respect to the bus stop. the bus will observe the car to have a speed of. if the bus was at rest relative to the bus stop, then the bus would observe the car to have a speed of 120km/h. rate your confidence to submit your answer. read about the concept need help? review these concept resources.

Explanation:

Step1: Identify relative - motion concept

The relative velocity of two objects moving in opposite directions is the sum of their velocities with respect to a common reference point.

Step2: Determine velocities

The bus is moving west at 60 km/h and the car is moving east at 60 km/h with respect to the bus - stop.

Step3: Calculate relative velocity

The relative velocity of the car with respect to the bus \(v = 60+60=120\) km/h.

Answer:

120 km/h
