Question

The velocity of a cart on a track traveling along the +x direction is plotted in the figure. 30 25 20 z0 25 25 Evaluate the x-acceleration of the cart at time t 6.6 seconds. Submit Answer Tries 0/10 Evaluate the x-acceleration at 16.3 seconds. Submit Answer Tries 0/10 Evaluate the x-acceleration at 20.9 seconds. Submit Answer Tries O/10 Evaluate the distance the cart travels from 18.0 seconds to 22.0 seconds. Submit Answer Tries 0/10

Answer 1

The important concept involved here is that the slope of the velocity-time graph gives us acceleration while area under the velocity-time graph gives us the displacement. And if the motion is in one direction, then the area gives distance traveled as well.

Then you need to carefully read the values for each point with scale at the top and right.
