Your favorite car goes zero to 60 mph in 3.5 seconds. Assuming it accelerates uniformly, sketch a velocity versus time graph of the motion. Two significant figures, the car travels ___ miles in 3.5 seconds.

Step 1

Assume car to be travelling in straight line. Let* u* be the car’s initial velocity, *v* be the car’s final velocity and *a* be the car’s acceleration. Use kinematics first equation to calculate the acceleration of the car as,

Step 2

Since, the acceleration is constant, the velocity-time curve is a straight line. It passes...
