The racing car has a mass of 1250kg. When the brake pedal is pushed down a constant braking force of 10,000 N is exerted on the car. Calculate the acceleration of the car.
If you could also tell me how you came to the answer, it would help me in the future. Thank you.
Force = mass x Acceleration
Rearrange the formula to
Acceleration = force/mass
acceleration = 10,000N/ 1250kg
acceleration = 8m/s^2
now remember this is an applied force to slow down the car (because the brakes are applied) therefore the car is not accelerating, it is decelerating.
you can write it as, the car is decelerating at 8m/s^2
double check with your teacher to write the answer in the format he wants (and to see if the questions is right) sometimes they tell you if ur wrong or right.
Also notice that N/kg = m/s^2
this is handy in future physics questions
Sure, I'd be happy to help you with that!
To calculate the acceleration of the car, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass.
In this case, the net force acting on the car is the braking force of 10,000 N. The mass of the car is given as 1250 kg.
Using the formula:
acceleration = net force / mass
we can substitute the given values:
acceleration = 10,000 N / 1250 kg
Simplifying the calculation, we find:
acceleration = 8 m/s^2
So, the acceleration of the car is 8 m/s^2.
I hope that helps! If you have any more questions, feel free to ask.
To calculate the acceleration of the car, we can use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration (F = m * a).
Given:
Mass of the car (m) = 1250 kg
Braking force (F) = 10,000 N
Using the formula F = m * a, we can rearrange it to solve for acceleration (a):
a = F / m
Substituting the given values, we get:
a = 10,000 N / 1250 kg
Simplifying the calculation:
a = 8 m/s²
Therefore, the acceleration of the car is 8 m/s².
To calculate the acceleration of the car, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
The formula to find acceleration is:
a = F/m
Where:
a = acceleration
F = net force
m = mass
In this case, the net force acting on the racing car is the braking force, which is constant at 10,000 N, and the mass of the car is given as 1250 kg.
Now, we can substitute the values into the formula:
a = 10,000 N / 1250 kg
Dividing 10,000 N by 1250 kg gives us:
a = 8 m/s²
Therefore, the acceleration of the racing car is 8 m/s².
