Question

a person is pushing on the stroller forward with a force of 45 newtons. friction is opposing the forward motion with a force of 45 newtons. if the stroller is moving at a constant speed of 2.5 meters per second, which graph shows the distance the stroller travels through time?

Explanation:

Step1: Recall the formula for constant - speed motion

The formula for distance $d$ in constant - speed motion is $d = vt$, where $v$ is the speed and $t$ is the time. Here, $v = 2.5$ m/s. This is a linear relationship between distance and time with a slope equal to the speed.

Step2: Analyze the characteristics of the graphs

A non - linear graph (curved) represents a non - constant speed (acceleration or deceleration). A horizontal line represents zero speed (object at rest). A downward - sloping line represents an object moving in the opposite direction. A linear upward - sloping line represents constant positive speed.

Answer:

The graph with a linear upward - sloping line starting from the origin represents the distance the stroller travels through time. So the correct graph is the one in the bottom - right corner.
