Question

David’s car has a mass of 2,000 kg and produces a force of 5,000 N. How fast will the car accelerate? How can you increase the acceleration of the car with the same amount of force?

a) The car will accelerate at 2.5 m/s². To increase acceleration, reduce the car's mass.
b) The car will accelerate at 2.5 m/s². To increase acceleration, increase the force applied.
c) The car will accelerate at 3.5 m/s². To increase acceleration, reduce the car's mass.
d) The car will accelerate at 3.5 m/s². To increase acceleration, increase the force applied.

Answer 1

The car will accelerate at 2.5 m/s². To increase acceleration, reduce the car's mass.

Step-by-step explanation:

To calculate the acceleration of the car, you can use Newton's second law of motion, which states that force equals mass multiplied by acceleration (F = ma). In this case, the force applied is 5,000 N and the mass of the car is 2,000 kg. Rearranging the equation, we can calculate the acceleration as acceleration = force / mass. Therefore, the car will accelerate at 2.5 m/s².

To increase the acceleration of the car with the same amount of force, you can reduce the car's mass. According to Newton's second law, acceleration is inversely proportional to mass. So, by decreasing the mass of the car, you will increase its acceleration. This can be achieved by removing unnecessary weight from the car.
