Aboy is pulling a toy wagon through a neighborhood at a speed of 0.75 m/s. a caterpillar in the wagon is crawling toward the rear of the wagon at a rate of 2.0 cm/s. what is the caterpillar’s velocity relative to the ground?

0.73 m/s in the forward direction

Explanation:

The caterpillar's velocity relative to the ground is given by:

where

is the velocity of the wagon with respect to the ground

v is the velocity of the caterpillar in the wagon's reference frame

In this situation we have

where the negative sign is due to the fact that the caterpillar is moving backward

Substituting,

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

i would say
