Question Discussion & Solution

Concept:

• Force: Force is a push or pull on an object. A force can cause an object to accelerate, slow down, remain in place, or change shape.

Force exerted = mass x acceleration

F = m × a

Acceleration = (Final velocity(v) - Initial velocity(u))/ time

\(a = \frac{{v - u}}{t}\)

Where F is the force exerted on the body, m is mass of the body, a is the acceleration of the body, v is final velocity, u is initial velocity and t s time.

Calculation:

Given,

Mass of body = 6 kg.

Change in velocity = (18 - 6) = 12 m/s

Time= 3 sec

Acceleration = 12/ 3 = 4m/s² 

Force = mass × acceleration

Force = 6 × 4 = 24 Newton.

Hence the correct option is 24 Newton

According to the given information,

Jaya ran faster than Sheetal

Jaya > Sheetal

Veena ran faster than Neha

Veena > Neha

Deepak ran faster than Neha but not as fast as Sheetal

Sheetal > Deepak > Neha

Sheetal ran slower than Veena but Veena is not the fastest.

Veena > Sheetal

Jaya > Veena > Sheetal > Deepak > Neha

Deepak came second last in the race.
