A student is playing with a simple helicopter toy and wants the toy to reach the height above it's initial position shown. The toy consists of a disc-shaped blade of mass 0.39kg and radius 0.07m and stick of negligible mass. The moment of inertia of any disc is I = /2mr?. Assume that the initial time is just after the student has released the toy, so the toy is spinning but NOT moving upwards, that the toy will lose 10) to air resistance during the flight and that it comes to rest and stops spinning at the final time. h = 19m What is the toy's moment of inertia? kg m2 v List the energy types at the initial and final time and whether work and loss (due to non- reference level conservative forces) occur as well as the corresponding amounts of energy. initial: RKE 72.7

Refer to the picture below. 

A student is playing with a simple helicopter toy and wants the toy to reach the height above it's initial position shown. The toy consists of a disc-shaped blade of mass 0.39kg and radius 0.07m and stick of negligible mass. The moment of inertia of any disc is I =1/½mr². Assume that the initial time is just after the student has released the toy, so the toy is spinning but NOT moving upwards, that the toy will lose 10] to air resistance during the flight and that it comes to rest and stops spinning at the final time. h = 19m What is the toy's moment of inertia? kg m2 List the energy types at the initial and final time and whether work and loss (due to non- reference level conservative forces) occur as well as the corresponding amounts of energy. initial: RKE 72.7 work? no work loss? loss final: GPE 72.7 With what rotational speed must the toy be launched? rad/s rpm I| || > > I| || >>
