Imagine two of the exact same shopping carts being pushed across the grocery store with the exact same amount of force. The two shopping carts are released simultaneously. They both keep going for a short distance. One of them moves with a greater acceleration than the other. Since they are the exact same cart and are pushed with the exact same force, which statement below describes a scenario in which it would be possible for one of them to have greater acceleration. Group of answer choices

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
