Question

How much force is required to produce an acceleration of 2ms2 by in a body of mass 0.8 kg

Answer 1

F = ma
= 0.8kg × 2m/s^2
= 1.6 N

1.6 N of force is required.

Answer 2

Answer:  1.6 N

Explanation:

• We know whenever we require to move an object or stop an moving object we need to apply force.
• When the object gains motion it acquires some velocity or speed.
• This change of speed with respect to time is known as acceleration.
• We know the fundamental formulae of force i.e., F = ma where m is the mass and a is the acceleration.
• F = 0.8 × 2

          =  $1.6\ kg.m/s^{2}$

          = 1.6 N

• Hence, the required force is  $1.6\ kg.m/s^{2}$ or 1.6 N
