A block is sliding without friction down a ramp along with a ring, a disc and a solid sphere. The height of the ramp is 50 meters. What is the speed of the ring? m/s Tries 0/2 What is the speed of the disc? m/s Tries 0/2 What is the speed of the solid sphere? m/s Tries 0/2 What is the speed of the block at the bottom of the ramp? m/s

Respuesta :

Answer:

Explanation:

All the objects are sliding and going down the ramp under the influence of gravity . So they all  will have the same velocity as a freely falling body under gravity have  . It is so because gravitational field is conservative .

So velocity of all of them ( it will not depend on mass )

= [tex]\sqrt{2gh}[/tex]

= 31.3 m/s
