Question

Suppose a bulldozer is being hauled at 50 km/h to a construction site on the back of a flatbed truck. From which reference point would the bulldozer not appear to be moving?

A. the road
B. a traffic light
C. the truck driver
D. a roadside tree

Answer 1

The bulldozer would not appear to be moving from the reference point of the truck driver.

Step-by-step explanation:

In this scenario, if the bulldozer is being hauled at a constant speed on the back of a flatbed truck, it would not appear to be moving from the reference point of the truck driver.

When we are inside a moving vehicle, objects within the vehicle appear to be stationary relative to us. So, the bulldozer on the flatbed truck would appear to be not moving from the perspective of the truck driver.

However, from the reference point of the road, a traffic light, or a roadside tree, the bulldozer would appear to be moving as the truck moves along the road.
