According to Newton's second law of motion, an unbalanced force has acted on the vehicle, causing its acceleration.

The force needed to give a 4.5 kg bowling ball an acceleration of 9 m/s^2 can be calculated using Newton's second law of motion:

Force = mass x acceleration

Force = 4.5 kg x 9 m/s^2

Force = 40.5 N

So the force needed is 40.5 Newtons.

To calculate the acceleration of a 32 kg object when a 6.75 N force is applied to it, we use Newton's second law of motion:

Force = mass x acceleration

Rearranging the equation, we have:

Acceleration = Force / mass

Substituting the given values, we get:

Acceleration = 6.75 N / 32 kg

Acceleration ≈ 0.21 m/s^2

So, the acceleration of the object is approximately 0.21 meters per second squared.
