Question

A body of mass 25000 gm is acted upon by a force of 5 N. Find
acceleration of the body in SI unit system.​

Answer 1

Answer:

m=25000/1000=25 kg and F=5N

Explanation:

acceleration=force /mass

a=25/5=5ms^-2

Answer 2

Given: Mass of the body = 25000gm

Forcing acting upon the body = 5N

To Find: acceleration of the body

Solution:

The SI unit for mass is kg

We know, 1kg = 1000gm

Mass in kg = Mass in gm /1000

Mass of the body in kg = 25000/ 1000

                                       = 25kg

We know, by Newton's second law, "The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object."

F = m x a, where F is the force acting upon the body, m is the mass of the body and a is the acceleration of the body.

5 = 25 x a

a = $\frac{5}{25}$

a = $\frac{1}{5}$

a = 0.2m/s²

Therefore, the acceleration of the body is 0.2m/s².
