A revolution equals 2*pi radians.
As the wheel rotates half every 4 seconds, then it means that it rotates half revolution.
Thus, the angular velocity of the wheel is given by:
w = (pi) / (4) = 0.79 rad / sec
answer
The wheel's angular velocity is 0.79 rad / sec
Answer:
1: the refracted angle in the first face is equal to the incident angle that is 60degrees
2. Emergence Angle is 42degrees

Answer: 132.02 J
Explanation:
By definition, the kinetic energy is written as follows:
KE = 1/2 m v²
In our question, we know from the question, the following information:
m = 0.1434 Kg
v= 42.91 m/s
Replacing in the equation for KE, we have:
KE = 1/2 . 0.1434 Kg. (42.91)² m²/s² ⇒ KE = 132.02 N. m = 132.02 J
Answer:
Torque = 50N x 0.3m = 15Nm
Explanation:
Torque = Force x length of lever arm. To obtain the torque simply multiply the two given values.
