If a car travels at 23 mi/h accelerates to 45 mi/h in 5seconds, the acceleration of the car is expressed as:
a = v-u/t
- u is the initial velocity
- a is the acceleration
- t is the time
a = 45-23/0.001388
a = 15,850.14mi/hr²
For the graph, the initial velocity will be 23mi/hr. The body will maintain a constant velocity for 5 seconds before decelerating for 5 secs. The required graph is as shown:
