What average net force is required to stop .

Click For Summary
To calculate the average net force required to stop a 1500 kg vehicle traveling at 75 km/h within 4.0 seconds, one must first determine the vehicle's acceleration. The formula F = ma applies, where F is force, m is mass, and a is acceleration. Acceleration can be found by converting the speed to meters per second and then using the change in velocity over time. It's crucial to ensure that all units are consistent during calculations. Understanding these principles will lead to the correct calculation of the required force.

What average net force is required to stop...

1. a 1500 kg vehicle is traveling at 75km/h. what is the average net force required to stop the vehicle within a 4.0 second interval?



2. f=ma? but i don't know acceleration?



3. force = 1500x (75/4) ?

You can find the acceleration with the information they give you in the problem. Look up the definition of acceleration. Also remember to make sure your units are consistent throughout your calculations.
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
