Question

If F=ma. The force =2000N applied by the car pulling the object. The mass pulled is 250kg. What is the acceleration of the car?What will happen to the acceleration if the mass of the object is increased? What will happen to the acceleration if the mass is decreased?

Answer 1

Given data

*The given force is F = 2000 N

*The given mass is m = 250 kg

The formula for the acceleration of the car is given as

`\begin{gathered} F=ma \\ a=(F)/(m) \end{gathered}`

Substitute the known values in the above expression as

`\begin{gathered} a=(2000)/(250) \\ =8m/s^2 \end{gathered}`

Hence, the acceleration of the car is a = 8 m/s^2

The mass and the acceleration are inversely proportional to each other. If the mass of the object is increased, then the acceleration of the object decreases.

If the mass of the object is decreased, then the acceleration of the object increases.
