Provide clear answers to the following questions at the end of your lab report.
- Use the law of conservation of mechanical energy to prove that the linear acceleration of a hoop rolling down an inclined plane (of angle θ) is given by Equation 6.1.
- Show similar proofs of Equations 6.2, 6.3, and 6.4.
a = 1/2 gsinθ (hoop) (6.1)
a = 2/3 gsinθ (solid cylinder) (6.2)
a = 3/5 gsinθ (spherical shell) (6.3)
a = 5/7 gsinθ (solid sphere) (6.4)

Rolling Without Slipping & Conservation of Mechanical Energy 1. A caveman applies a horizontal force of 800 N at height of 0.1 m above the center of a large spherical boulder of mass 400 kg and radius of 0.5 m (treat as a sphere: lon-2/5 mr2). Assume the sphere starts from rest and rolls horizontally without slipping. a) Draw a free-body diagram and label all the forces at their point of contact. b) Write equations applying Newton's 2 nd law...
