Question

How much force is needed to accelerate a trolley of mass 20g through 1 m/s2?

Answer 1

Answer:

0.02 N

Explanation:

First we will convert 20 g into kg

Then, 0.02 kg

F = ma

= 0.02*1

=0.02 N

Answer 2

Answer:

The correct answer to this question is $0.02 N$.

Explanation:

Given:-  Mass of the trolley is $20 g$

              Acceleration of the trolley is $1 m/s2$

We need to find the force that is exerted on the trolley.

We can find the force as mass multiplied by acceleration.

Acceleration is the rate of change of velocity with the time in the terms of both direction in the speed.

The mass is defined as the measure of amount of matter that contain in that physical body.

In this question, the masses are given in the terms of a gram. But we need to find that in the terms of KG as per the formula.

Therefore, as per the question given, the equation which will suit her perfectly will be.

$F = ma= 0.02*1=0.02 N$

Therefore,  The correct answer to this question is $0.02 N$.
