Question

A pumpkin with a mass of 2.5 kg was pushed toward a wall. The average acceleration of the pumpkin was 10.7 m/s².

How much force was applied to the pumpkin to make it move?
1. 4.28 N
2. 26.75 N
3. 4.28 m/s²
4. 26.75m/s²

Answer 1

F=m.a
<=> F= 2.5 x 10.7
<=> F= 26.75 N
=> 2 is correct answer

Answer 2

The correct option is 2.

Explanation:

The formula of force is

`F=ma`

Where, F is force, m is mass of the object and a is acceleration.

A pumpkin with a mass of 2.5 kg was pushed toward a wall. The average acceleration of the pumpkin was 10.7 m/s².

Put m=2.5 and a=10.7 in the above formula.

`F=2.5* 10.7`

`F=26.75`

Unit of force is N.

Therefore the force was applied to the pumpkin to make it move is 26.75 N. The correct option is 2.
