Final answer:
The subject of this question is Physics. Dragsters can reach a top speed of 145 m/s in only 4.45 seconds. The final velocity is greater than the average acceleration because the assumption of constant acceleration is not valid for a dragster.
Step-by-step explanation:
The subject of this question is Physics. Dragsters can reach a top speed of 145 m/s in only 4.45 seconds. To calculate the average acceleration of the dragster, you can use the formula: average acceleration = (final velocity - initial velocity) / time. The final velocity of the dragster can be found by multiplying the acceleration by the distance traveled without using any information on time.
The final velocity is greater than the average acceleration because the assumption of constant acceleration is not valid for a dragster. A dragster changes gears, so the acceleration would be greater at the beginning than at the end. This would have an effect on the final velocity, which would be less than 162 m/s.
