Question Cylinder A has a mass of 2kg and cylinder B has a mass of 10kg. Determinethe velocity of A after it has displaced 2m from its original starting position. Neglect the mass of the cable and pulleys and assume that both cylinders start at res

The velocity of A is 5.16m/s² Explanation: Given- mass of cylinder A, mₐ = 2kg mass of cylinder B, mb = 10kg Distance, s = 2m Velocity of A, v = ? Let acceleration due to gravity, g = 10m/s² We know, [tex]a = \frac{mb * g – ma * g}{ma + mb} \\\\a = \frac{10 * 10 – 2 * 10}{ 2 + 10} \\\\a = \frac{80}{12} \\\\a = 6.67m/s^2[/tex] We know, [tex]v = \sqrt{2as}[/tex] [tex]v = \sqrt{2 X 6.67 X 2} \\\\v = \sqrt{26.68} \\\\v = 5.16m/s^2[/tex] Therefore, the velocity of A is 5.16m/s² Log in to Reply

The velocity of A is 5.16m/s²Explanation:Given-

mass of cylinder A, mₐ = 2kg

mass of cylinder B, mb = 10kg

Distance, s = 2m

Velocity of A, v = ?

Let acceleration due to gravity, g = 10m/s²

We know,

[tex]a = \frac{mb * g – ma * g}{ma + mb} \\\\a = \frac{10 * 10 – 2 * 10}{ 2 + 10} \\\\a = \frac{80}{12} \\\\a = 6.67m/s^2[/tex]

We know,

[tex]v = \sqrt{2as}[/tex]

[tex]v = \sqrt{2 X 6.67 X 2} \\\\v = \sqrt{26.68} \\\\v = 5.16m/s^2[/tex]

Therefore, the velocity of A is 5.16m/s²
