Homework Equations
a=meu*g
The Attempt at a Solution
meu= 20/10
= 2
The answer's wrong
The normal force here is the driving force of the vehicle, which is it's mass times the accelerationSuraj M said:Myu*g? What is that suppose to be?
Don't just apply the formula you've learnt,
Identify the normal force
You've got the concept right. Check the math again.Priyadarshini said:The normal force here is the driving force of the vehicle, which is it's mass times the acceleration
The firctional force is meu*normal force, so the frictional force is meu*M*aSuraj M said:Exactly so the formula for frictional force is?
Do you thing myu*g represent the frictional force now?
Isn't the acceleration 20m/s^2 for both the blocks?cnh1995 said:What is the acceleration of the smaller block?
Have you drawn a free body diagram showing the forces acting on the smaller mass, or do you feel like you have advanced to the point where you no longer need to use free body diagrams?Priyadarshini said:Isn't the acceleration 20m/s^2 for both the blocks?

cnh1995 said:Yes. That is what is needed. Write the equation for forces "on" the smaller block. You'll get the value of friction coeff just to avoid slipping. You'll see Chestermiller's reply makes true sense!
I knew the FBD would do the trick.Priyadarshini said:View attachment 95008
Got it! Thank you!
A frictional coefficient is a numerical value that represents the amount of resistance or friction between two surfaces in contact with each other.
Frictional coefficient is typically measured using a device called a tribometer, which applies a known force to the two surfaces and measures the resulting frictional force. The ratio of these two forces is the frictional coefficient.
The frictional coefficient can be affected by several factors, including the roughness and texture of the surfaces, the type of material the surfaces are made of, and the amount of force applied.
The frictional coefficient is important because it helps us understand and predict how much resistance or friction will occur between two surfaces. This information is crucial in many applications, such as designing machinery and optimizing performance.
Yes, the frictional coefficient can be changed by altering the factors that affect it. For example, using a lubricant can reduce the frictional coefficient between two surfaces, while increasing the force applied can increase the frictional coefficient.
