Question

A van moves with a speed of 70 km/h accelerates to 90 km/h in 10 seconds while a car accelerates from a speed of 36 km/h to 60 km/h in 8 seconds. Is the acceleration of the van is more than the acceleration of the car? Show your calculation to support your answer.

Answer 1

The acceleration of the car is more than the acceleration of the van.

Step-by-step explanation:

To compare the acceleration of the van and the car, we need to calculate their acceleration values. Acceleration can be calculated using the formula:

Acceleration = (Final Velocity - Initial Velocity) / Time

For the van:

Acceleration of the van = (90 km/h - 70 km/h) / 10s = 2 km/h/s

For the car:

Acceleration of the car = (60 km/h - 36 km/h) / 8s = 3 km/h/s

Therefore, the acceleration of the car is more than the acceleration of the van.
