A yo-yo has a rotational inertia of 1140 g·cm2 and a mass of 81.3 g. Its axle radius is 3.27 mm, and its string is 106 cm long. The yo-yo rolls from rest down to the end of the string.
(a) What is the magnitude of its linear acceleration?
(b) How long does it take to reach the end of the string? As it reaches the end of the string, what are its
(c) linear speed,
(d) translational kinetic energy,
(e) rotational kinetic energy, and
(f) angular speed?
Can you please help me set this problem up? Suppose that now you want to make a scale model of the solar system using the ball bearing .0014 m to represent the sun. (a) How far from it would you place a sphere representing the earth?
A car traveling at 21 {rm m/s} runs out of gas while traveling up a 25^circ slope. How far up the hill would it coast before starting to roll back down.
the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 N. Find out the acceleration of the sled and child.
The counterbalance w1 weighs 100 N. Find out the weight w2 and the angle α needed so that no force is exerted on the hip joint by the leg plus cast.
Using energy considerations, compute the average force the beam exerts on the pile driver while the pile driver is brought to rest.
A certain telescope has an objective of focal length 1580cm. If the Moon is used as an object, a 1.4 cm long image formed by objective corresponds to what distance, in miles, on the Moon? Suppose 3.8 multiplied by 108 m for the Earth-Moon distance..
A sailor strikes the side of his ship just below the surface of the sea. He hears echo of the wave reflected from the ocean floor directly below 9 s later. How deep is the ocean at this point.
How several 90-rm W, 120-rm V light bulbs can be connected to a 20-rm A, 120-rm V circuit without tripping the circuit breaker.
Setting a world record in a 100m race, Maggie and Judy cross the finish line in a dead heat, both taking 10.0 s. Accelerating uniformly, Maggie took 2.0 s and Judy 2.5 s to attain maximum speed that they maintained for the rest of race.
assume you are standing on a train, both feet together, facing a window. The front of the train is to your left. The train starts moving forward.
What is magnitude of the momentum
