Question

A force of 45 N is exerted on an object, resulting in an acceleration of 5 m/s2 for the object. What will the object's acceleration be if the force doubles? Question 3 options: 2. 5 m/ s2 5 m/ s2 10 m/ s2 20 m/ s2.

Answer 1

The acceleration will be 10 m/s² if the force is doubled. Option C is correct.

What is Force?

It can be defined as the product of the mass of the object and its acceleration.

$F = m a$

Where,

$F$ - force = 45 N

$m$- mass = ?

$a$ - acceleration = 5 m/s²

Now, put the values in the formula,

$45 = m \times 5 \\\\ m = \dfrac {45 }{5}\\\\ m = 9\rm \ kg$

Now if force doubled then the acceleration will be

$a = \dfrac {2 \times 45} {9}\\\\ a = 10 \rm \ m/s^2$

Therefore, the acceleration will be 10 m/s² if the force is doubled.
