Question

A car of mass 2000 kg is moving on a straight road with constant velocity of 2 metre per second net force acting on the car is

Answer 1

Answer:

Given:

Mass of car = 2000 kg

Velocity = 2 m/s

To find:

Net force acting on the car

Formulas used:

F = m × a,

where m is mass and a is acceleration.

Concept:

Please read the question carefully.

You will notice that it has been given that the car moves in constant Velocity of

2 m/s.

This means that the net acceleration on the car is zero (0).

So "a" is zero (0).

Calculation:

Net force = Mass × acc.

=> Net force = mass × 0

=> Net force = 0 N.

Answer 2

Given :----

• Mass = 2000kg
• Constant velocity = 2m/s

To Find :---

• Net force acting on car ?

Solution :-----

Constant velocity means uniform motion ....

So, acceleration is equal to zero....

⛬ force acting on it = Mass × acceleration

→ Force = 2000 × 0

→ Force = 0 ..

[✰ in this condition there will only be gravity acting on it because remember Newton first law. If body is in uniform motion, it will continue to do so without any need of force.. ]

So, Force Acting is Zero.....
