Hello, Would you be able to show me step by step solution?
The time dependence of the angular velocity of a rotating body is expressed by the equation: ω = 2 + 0.5t. How many times does the body turn in the first 20 s from the start of the rotation?
Thank you !
A cable is being pulled off a drum of radius r = 2.28 m with a velocity v. At the instant shown, v is increasing at the rate 3.7 m/s2. What is the angular acceleration (in rad/s2) of the drum about its center at this instant?
Can you help me with this problem?There exists a 0.35 m radius turntable that has a constant angular acceleration of 0.145 rad/s2 from rest. How many times does this turntable rotate in 12 seconds after the acceleration begins? After the acceleration begins, how long does it take for the magnitude of the acceleration of a point on the rim of the turntable to reach 0.12 m/s2?
