Much better. Now in your post #1, what does the 0.98 represent, and what does the 0.30 represent (including their units)?Infinite324 said:The mass of the garbage can is 30 kg. The coefficient of the static friction between the can and the ground is .75.
What is the horizontal force necessary to get the can moving?
It should be 9.8 m/s/s. How did the 30 kg become 0.30?Infinite324 said:.98 m/s/s represents gravity and sorry I typed it wrong. It should be 30 N
According to your understanding, you tell me. You almost had it right to start with.Infinite324 said:Wow yes 9.8 for Gravity. How should I continue then?
If you're not sure about this, you need to go back and review your text and/or notes. The objective of studying a course is so that you can understand the fundamentals (and use this to solve a wide array of problems), rather than just to solve one specific problem.Infinite324 said:Should I multiply (9.8)(30)(.75)?
To calculate horizontal force, you need to use the formula F = μs * m * g, where F is the horizontal force, μs is the coefficient of static friction, m is the mass of the object, and g is the acceleration due to gravity.
The coefficient of static friction is a measure of the amount of friction between two surfaces that are not moving relative to each other. It is a dimensionless number that is specific to the two surfaces in contact.
The mass of an object directly affects the horizontal force required to move it, as seen in the formula F = μs * m * g. The greater the mass, the greater the horizontal force needed to overcome static friction and move the object.
Yes, the coefficient of static friction can change depending on the surfaces in contact and the conditions under which they are in contact. For example, it may change if the surfaces are wet or if there is debris present.
Static friction is the force that must be overcome to start an object in motion, while kinetic friction is the force that opposes the motion of an object that is already in motion. The coefficient of static friction is typically higher than the coefficient of kinetic friction.
