- A tire is rotating at an angular velocity of 51.6 radians/s. The radius of the tire is 1.9 m. Find the linear speed/velocity of a point on the edge of the tire.Due to the rotation of the forked rod, the ball in the figure shown travels around the slotted path, a portion of which is in the shape of a cardioid, r = 0.5(1 – cose)ft , where e is in radians. If the ball's velocity is v = 4ft/s and its acceleration is a = 30ft/s² at the instant 0 = 180°, determine the angular velocity Ô and angular acceleration Ö of the fork. r = 0.5 (1- cos 0) ftPlease help me with this

Find the time needed for wheel C to reach an angular speed of 50.5 rev/min, assuming the belt does not slip. (Hint: If the belt does not slip, the linear speeds at the two rims must be equal.) Number i UnitsSomeone frequently throws a tennis ball for their dog to chase.Throughout the throwing motion, the angular velocity of their arm is 6.7radians/s, and the radius of rotation of the ball is 63.0 cm.One day they decide to test out a ball-throwing tool which effectivelyextends the radius of rotation by an extra 36 cm. Assuming all othervariables are equal, how much faster (in m/s) can they throw the ballwhen they use the launcher compared to when they don't?Express your answer to 2 decimals, and don't include units+.

- A turntable 46.0 cm in diameter diameter starts from rest, and rotates at 68.0 rpm at its first complete revoļution with constant angular acceleration. If it maintains the same acceleration, a) what is the rotational speed at time 34.0 seconds? b) what is the tangential speed of a point 10 cm from the edge of the turntable at time 34.0 seconds? Enter answer "O" in the answer box. Submit in the corresponding folder (or email) your solution by 3:50 pm, include a sketch/drawing of the rotating wheel, and a step- by-step solution.Answer the question in full details, thank you very much: The tub of a washer goes into its spin cycle, starting from rest and gaining angular speed steadily for 8.21 s,when it is turning at 4.99 revolutions/s. At this point the person doing the laundry opens the lid, and a safetyswitch turns off the washer. The tub smoothly slows to restin 11.6 s. Through how many revolutions does the tub turn while it is in motion?Consider the 13 kg motorcycle wheel shown in the figure. Assume it to be approximately a ring with an inner radius of 0.285 m and an outer radius of 0.325 m. The motorcycle is on its center stand, so that the wheel can spin freely. If the drive chain exerts a force of 2200 N at a radius of 4.95 cm, what is the angular acceleration of the wheel, in radians per square second? What is the tangential acceleration, in meters per square second, of a point on the outer edge of the tire? How long, in seconds, starting from rest, does it take to reach an angular velocity of 89.5 rad/s?
