Answer:
The coefficient of kinetic friction is 1.03
Explanation:
<u>Step 1:</u> Given data
⇒ mass of the block = 0.600 kg
⇒ elastic constant k = 20 N/m
⇒ The spring is compressed by 20.0 cm (=x) = 0.2 m
⇒ Once it loses contact with the spring, the block travels a distance 33 cm
<u>Step 2:</u> Calculate the potential energy
Ep = 1/2 * k * x²
Ep = 1/2 * 20N/m * (0.2m)²
Ep = 0.4 Nm
<u>Step 3:</u> Calculate the coefficient of kinetic friction
At the end of the movement Potential energy = work
W = Ep = 0.4Nm = µx * m * g* x
µx = Ep / (m*g*x)
µx = 2Nm / ( 0.6 kg * 9.81 m/s² * 0.33m)
µx = 1.03
The coefficient of kinetic friction is 1.03
Answer:
atomic mass (12.0 grams) of carbon is equal to exactly 1 mole of carbon.So the Ans is Carbon
Explanation:
Answer:
-2 m/s^2
Explanation:
Acceleration is equal to the slope of the graph. You just find the slope of that section. The rise is -20 and the run is 10, so you get -2.
since centripetal acceleration is always towards the center of the circle
so at the given position where speed and acceleration is given the center coordinate will be towards the center of circle
also we know that
so the coordinates of the center will be
so the coordinate is (3.20 m, 4.04 m)
