Question

calculate the acceleration prodused in a body of 50g by applying a force of 1N​

Answer 1

20 m/s² is the required answer.

GIVEN:

• Mass of body, m = 50 g

• Force, f = 1 N

TO FIND:

Acceleration produced in the body , a

FORMULA:

According to Newton's second law of motion,

f = ma

SOLUTION:

STEP 1: TO CONVERT MASS IN STANDARD UNITS

• The standard unit of mass is kilogram, kg

• 1 gram = 10^-3 kg

• 50 g = 50× 10^-3 kg

• Mass, m = 5× 10^-2 kg

STEP 2: TO FIND ACCELERATION

f = ma

a = f/m

a =1 / (5 × 10^-2)

a = 10² / 5

a = 100 / 5

a = 20 m/s²

Acceleration, a = 20 m/s²

ANSWER:

Acceleration produced in the body is 20 m/s²

NEWTON'S SECOND LAW OF MOTION:

• The law states that force is equal to the rate of change of momentum of body.

• f = dp/dt

• f = ma is the result of Newton's second law of motion, when mass is constant.

• Here force is defined as the product of mass and acceleration.
