Question

g Calculate the final speed of a solid cylinder that rolls down a 5.00-m-high incline. The cylinder starts from rest, has a mass of 0.750 kg, and has a radius of 4.00 cm.

Answer 1

`V=8.08m/s`

Step-by-step explanation:

From the question we are told that:

Height
`h=5.00m`

Mass
`m=0.750kg`

Radius
`r=4.00cm=>0.04m`

Generally the equation for Total energy is mathematically given by

`mgh=(1)/(2)mv^2+(1)/(2)Iw^2`

Therefore

`V=\sqrt{(4gh)/(3)}`

`V=\sqrt{(4*9.8*5)/(3)}`

`V=8.08m/s`
