I could use help with these problems it's been awhile since I've done any physics thanks!

PreLab PHY 122: 1D Motion 1. A cart is moving along a horizontal track away from a motion detector. The motion diagram below shows the position of the cart at equal time intervals. The arrows represent the instantaneous velocity at each position. Describe the kind of motion this particle is undergoing and explain why (how is the velocity, acceleration, etc... Start 2.

Sketch the graphs of position, velocity, and acceleration vs. time for this motion as described by the data collected by the motion detector Start MacBook Air F8 F7 F6 F5 F4

Explanation / Answer

1] From the given image, it can be said that the points are not equidistant from each other and thus the position is not changing linearly with time. Also, the velocity of the cart does not have the same magnitude at every point. The velocity increases with time and thus the cart is undergoing an accelerated motion to the right with constant acceleration.

2]

A] Similar to the reasoning given above, the cart is undergoing a constant acceleration (varying velocity with time). This is apparent from the length of the arrows denoting the instantaneous velocities at every point.

B] The position vs time graph will be an upwards parabola because the position is not changing linearly with time (and that the velocity itself is increasing with time).

The velocity vs time graph will be a straight line with a constant non-zero slope showing a positive acceleration.

Acceleration vs time graph will be a horizontal line with zero slope denoting the acceleration does not change with time.
