The approximate speed of the cart at low, medium and high speed after the stated seconds are 55cm/s ; 120cm/s and 63cm/s respectively.
Estimate of the cart speed for the different fan speeds can be obtained from the attached graph.
- The low fan speed is marked blue :
- The elapsed time is on the x - axis
- Cart speed after 3 seconds; is the where the line drawn from x intersects the blue line
- This is approximately 55cm/s.
- The medium fan speed is marked yellow :
- The elapsed time is on the x - axis
- Cart speed after 5 seconds; this is where the line drawn from point marked 5 on the x-axis intersects the yellow line
- The reading on the y - axis is approximately 120cm/s.
- The high fan speed is marked green :
- The elapsed time is on the x - axis
- Cart speed after 2 seconds; this is where the line drawn from point marked 2 on the x-axis intersects the green line
- The reading on the y - axis is approximately 63cm/s.
Therefore, the approximate speeds for any of the time interval can be obtained from the graph.
