Suppose that a solid ball, a solid disk, and a hoop all have the same mass and the same radius. each object is set rolling without slipping up an incline with the same initial linear (translational) speed. which object goes farthest up the incline?

Hoop will reach the maximum height

Explanation:

let the mass and radius of solid ball, solid disk and hoop be m and r  (all have same radius and mass)

They all  are rolled with similar initial speed v

by the law of conservation of energy we can write

for solid ball

putting in the above equation and solving we get

now for solid disk

putting in the above equation and solving we get

for hoop

putting in the above equation and solving we get

clearly from the above calculation we can say that the Hoop will reach the maximum height

less than one you can't create energy

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
