Home Insert 10 Draw B layout T Review U ab View D A A Clear Formatting A DO A E L 15. A wheel turns on an axle. No matter the size of the wheel, the axle will always rotate at I rotation per second. Initially you place a wheel on the axle with a radius of 0.5 meters. You then replace that wheel with another wheel with a radius of 1 meter. Both wheels have the same mass. (use 1 kg). What is the angular momentum when you use the small wheels? What is the linear speed of a vehicle with the wheels described in the first example(small)? What is the angular momentum when you use the larger wheels? What is the linear speed of a vehicle with the larger wheels?
