The position time graph for the car and truck for time
Explanation of Solution
Given info:
Car is at rest at time
Car is accelerating constantly at
At time
Formula used:
Formula to find the distance travelled in term of velocity and time is,
Another formula to find the distance travelled in term of speed and acceleration is,
Here,
To draw a position versus time graph we have to draw a table showing position of car from time
Find the position of car:
As car is starting from rest its initial velocity is zero. Finding the position of car using equation-2.
By changing the value of time in equation-3 from
Time | |||||||
Position of car ( ) |
Find the position of truck using equation-1.
By changing the value of time in equation-4 from
Time | |||||||
Position of car ( ) |
We draw position time graph by taking value of time on x-axis and position on y-axis.
The shape of position time graph for car is curve and for truck is a straight line.
Graph shows car is accreting from rest and truck is moving with constant velocity.
Conclusion:
Thus,the shape of position time graph for car is curve and for truck is straight line.
Graph shows car is accreting from rest and truck is moving with constant velocity.

Jets are catapulted into airspace from the deck of an aircraft carrier with two sources of propulsion: the jet propulsion and the catapult. At the point of leaving the deck of the aircraft carrier, the F-35’s acceleration decreases to a constant acceleration of 5.0m/s2 at 30 with respect to the horizontal.
