Question

1- Calculate the force needed to speed up a car with a rate of 5ms–2, if the mass of
the car is 1000 kg. (answer with correct solution)
​

Answer 1

Answer:

5000N force

Explanation:

Acceleration=5m/s²

Mass=1000kg

Force=ma

= 1000×5

=5000N

Answer 2

Answer:

Explanation:

Given :-

Mass of the car, m = 1000 kg

Rate of acceleration, a = 5 m/s²

To Find :-

Force, f = ??

Formula to be used :-

Force = mass × acceleration

Solution :-

Putting all the values, we get

Force = mass × acceleration

⇒ Force = (1000 × 5) Newton

⇒ Force = 5000 Newton

Hence, the force needed to speed up a car is 5000 Newton.

Important Term :-

Force  - Force is the agency which can change the state of rest or of uniform motion or shape or direction of motion of body. It is vector quantity. The unit of force in MKS system is newton.
