A solid spherical jewel rolls smoothly from rest down a ramp. The jewel descends a vertical height of 1.2m to reach the bottom of the ramp. What is the jewel's speed at the bottom of the ramp? Hint: This problem has nothing to do with elasticity as we did not formally cover that topic, and the inertia of a solid sphere is found by 2/5 m r2
Hello, can you help me with this problem please? Thank you!
A frictionless pulley has the shape of a uniform solid disk of mass 2.90 kg and radius 10 cm. A 1.30 kg stone is attached to a very light wire that is wrapped around the rim of the pulley (the figure (Figure 1)), and the system is released from rest. How far must the stone fall so that the pulley has 3.40 J of kinetic energy? What percent of the total kinetic energy does the pulley have?
