20 kg object travels 28 meter and stops. coefficient friction= 0.085 how much work was done by friction?

Physics

Tresset [83]3 years ago
7 0
Assuming it is on a horizontal surface:
friction = μR
R = 20g (g is gravity 9.81)
so Friction = 0.085 x 20g
Work done is force x distance 
so Work done = 0.085 x 20g x 28
 = 466.956 J

What is the net force on an object that has balanced forces acting on it?
sergij07 [2.7K]

Answer:

This is what is meant by the concept of “net force.” the net force acting on a body is the sum total of all the individual force vectors acting on the object. When this net force is non-zero, we say the forces are unbalanced. When the net force is 0, we say that the forces are balanced.
