Question

A race car exerts 19,454 n while the car travels at a constant speed of 201 mph, 91.36 m/s.what is the mass of the car?

Answer 1

A race car exerts 19,454 n while the car travels at a constant speed of 201 mph, 91.36 m/s. the mass of the car can be solve by using the formula F= mg, where g is the acceleration due to gravity

M = 19, 454 N/ 9.81 m/s2

M = 1,983.08 kg

Answer 2

The mass of the car is 1985.10 kg.

Step-by-step explanation:

It is given that,

Force exerted by the race car, F = 19,454 N

The constant speed of the car, v = 201 mph

We need to find the mass of the car. Let it is given by m. It can be calculated using Newton's second law of motion. It is given by :

`m=(F)/(a)`

The car is exerting this force under the action of gravity. Here, a = g

`m=(F)/(g)`

`m=(19454\ N)/(9.8\ m/s^2)`

m = 1985.10 kg

So, the mass of the car is 1985.10 kg. Hence, this is the required solution.
