A car with a mass of 1.2 x 10^3 kilograms starts from rest and attains a speed of 20 meters/seconds in 5 seconds. What net force

muminat

The mass of the car [m] = 1.2×10^3 kg.

The initial speed of car[u]= 0 m/s

The final speed of car [v]= 20 m/s

We are asked to calculate the force required to increase the speed from 0 to 20 m/s.

The momentum of a substance is defined as product of mass and velocity.

Mathematically momentum p=m×v [Here m is the mass]

From Newton's second law we know that-

$F=\frac{dp}{dt}$

$F=\frac{mv-mu}{t}$ [here t is the time]

$= \frac{1200*20-0}{5}\ N$

$=\frac{24000}{5} \ N$

$=4800\ N$

$= 4.8*10^{3} \ N$ [ANS]

Hence the correct answer to the question is C.
