Question

The acceleration of The Munster’s car is 9.71 m/s2 when he applies 5050 N of net force (by way of the engine). What is the mass of his car in kilograms?

520 kg


49,000 kg


0.0019 kg


none of the above

Answer 1

Force is defined as the product of mass of the body and its acceleration.

In the question we are given,

Force (F) = 5050 N

Acceleration (a) = 9.71 m/
`s^(2)`

Now, According to Newton's second law of motion ,

F= m*a

Dividing both sides by a, we get

`(F)/(a)`=m

or,

m=
`(F)/(a)`

Putting the values of F and a we get,

m=
`(5050)/(9.71)`

m=520.08 kg

Hence, the mass of Munster's Car ≈ 520 kg.

Answer: 520 kg
