Arolling (without slipping) hoop with a radius of 0.27 m and a mass of 1.80 kg climbs an incline. at the bottom of the incline, the speed of the hoop's center-of-mass is vi = 8.90 m/s. the incline angle is not needed in this problem. what is the angular speed of the hoop's rotation? enter a number rad/s (5 attempts remaining)input 1 status what is the hoop's translational kinetic energy at the bottom of the incline? enter a number j (5 attempts remaining)input 2 status what is the hoop's rotational kinetic energy at the bottom of the incline ? the hoop's moment of inertia is mr². (since its mass is concentrated on the edge). enter a number j (5 attempts remaining)input 3 status find the maximum (vertical) height h the hoop reaches on the incline.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
