(mu s) is the coefficient of kinetic friction, <span> (mu k) is a normal force,</span>
Answer:
Explanation:
It's called static equilibrium. The object is motionless and every force equals/cancels each other out
Answer:
I believe it has 4 legs as well
Explanation:
It looks like 4 legs, it never gets on 2 legs so it should be 4.
The thermal energy used by the tires is 1.14 J.
Here, the thermal energy used will be the work done by Mark.
Given,
Distance = 140 m
Force exerted = 160 N
Thermal energy = ?
We know,
Work = force * displacement
But here the thermal energy of tires is asked.
In this question, the thermal energy used is the energy consumed to do the work.
So, using the formula of work we can find the thermal energy.
W = 160 / 140 = 1.14 J
Therefore the thermal energy used by the tires is 1.14J
