Question

An object moving with an acceleration of 4m/s square is acted upon by a force of 20Newton. Calculate the mass of the object.​

Answer 1

Given :

▪ Acceleration of object = 4m/s²

▪ Applied force = 20N

To Find :

▪ Mass of the object.

Concept :

☞ As per newton's second law of motion, Force is defined as the product of mass and acceleration.

☞ Force is a vector quantity.

☞ It has both magnitude as well as direction.

☞ SI unit : N

☞ Dimension formula : [M(1)L(2)T(-2)]

Calculation :

→ F = m × a

→ 20 = m × 4

→ m = 20/4

→ m = 5kg

Answer 2

Answer:

given:

acceleration=a=4m/s^2

force=20N

to find: mas of object

solution:

F=m x a

20=m x 4

20/4=m

5kg =mass
