1. A wheel moves in a circle with a speed of 4.5 m/s. The acceleration is 8.8 m/s/s. The speed is increased to 9.0 m/s (i.e., doubled). The new acceleration would be m/s/s. (the radius of the circle is not changed.) 2. A barrel has a radius of 6.90 m. An acceleration of 8.75 m/s/s once up to speed is shown. Find the speed moving at Find the time for the barrel to make one complete revolution 3. A wheel ride takes riders on a spin at 17.8 mi/hr (7.94 m/s). The radius of the circle is 7.49 m. Determine the time for outside riders to make one complete circle, Determine the acceleration of the riders. 4, Jade navigated on the path that was of a circular are with a radius of 42.9 m. She made the turn at 7.04 m/s. What was her acceleration on the turn? 5, An airplane flying at a speed of 113 m/s makes a turn. The co-pilot has to keep the acceleration under 3.26 m/s/s. What is the minimum turning radius that the plane can have in order for the acceleration to be less than 3.26 m/s/s? 6. Toby holds Kate by the hand and swings her in a circle while she maintains her blades on the ice, stretched out in a nearly horizontal orientation. Determine the net force that must be applied to Kate (m = 50.5 kg) if her center of mass rotates in a circle with a radius of 0.807 m once every 1.28 seconds
