Calculate the frictional force on the crate.
Calculate the coefficient of kinetic friction between the crate and the floor.
I got the normal force, 363 N. Now just need help with these two following problems. Please and thank you!
friction=13 N
13=mu*37*9.8
mu= 13/(37*9.8)
frictional force = force applied - force of motion
In this case, the force applied is 50.0 N (the horizontal force) and the force of motion can be calculated using Newton's second law:
force of motion = mass * acceleration
So, substituting the given values:
force of motion = 37.0 kg * 1.00 m/s^2 = 37.0 N
Now, you can calculate the frictional force:
frictional force = 50.0 N - 37.0 N = 13.0 N
Therefore, the frictional force on the crate is 13.0 N.
To calculate the coefficient of kinetic friction between the crate and the floor, you need to use the formula:
coefficient of kinetic friction = frictional force / normal force
The normal force can be calculated using the equation:
normal force = mass * acceleration due to gravity
Substituting the given values:
normal force = 37.0 kg * 9.8 m/s^2 = 363.6 N (approximately)
Now, you can calculate the coefficient of kinetic friction:
coefficient of kinetic friction = 13.0 N / 363.6 N ā 0.036
Therefore, the coefficient of kinetic friction between the crate and the floor is approximately 0.036.
Net force = Applied force - Frictional force
Given:
Mass of the crate (m) = 37.0 kg
Applied force (F) = 50.0 N
Acceleration (a) = 1.00 m/sĀ²
Using Newton's second law, we can rearrange the equation to solve for the frictional force:
Frictional force = Applied force - Net force
Net force = mass Ć acceleration
Net force = 37.0 kg Ć 1.00 m/sĀ²
Net force = 37.0 N
Frictional force = 50.0 N - 37.0 N
Frictional force = 13.0 N
Therefore, the frictional force on the crate is 13.0 N.
To calculate the coefficient of kinetic friction between the crate and the floor, you can use the formula:
Coefficient of kinetic friction (Ī¼) = Frictional force / Normal force
Given:
Frictional force = 13.0 N
Normal force = 363 N
Coefficient of kinetic friction = 13.0 N / 363 N
Coefficient of kinetic friction ā 0.036
Therefore, the coefficient of kinetic friction between the crate and the floor is approximately 0.036.
