A thin uniform cylindrical turntable of radius 2.7 m and mass 22 kg rotates in a horizontal plane with an initial angular speed
Marizza181 [45]

Answer:

8.59 rad/s

Explanation:

Given that:

A thin uniform cylindrical turntable radius = 2.7 m

with a mass (M) = 22 kg

initial angular speed (ω₁) =  12 rad/s

Mass of the clump of the clay (m) = 11 kg

Diameter (d) from the point of rotation = 1.7 m

We are to find the final angular  velocity  (ω₂) ,To do that; we apply the conservation of annular momentum; which is as follows:

L₁ = L₂

l₁ω₁ = l₂ω₂

( 0.5 × M × r²) × ω₁ = (0.5 × M × r² + md²) ω₂

Making ω₂ the subject of the formula ; we have:

\omega_2 = \frac{(0.5*M*r^2)* \omega_1}{(0.5*M*r^2+md^2)}

\omega_2 = \frac{(0.5*22*2.7^2)* 12}{(0.5*22*2.7^2+11*1.7^2)}

\omega_2 = 8.58 rad/s

Hence,  the angular speed of the clay and turntable = 8.59 rad/s

Y’all this assignment determines if i pass , please help me out.. Part 2: Graphing the Effect of Changing Mass and Velocity on K
jarptica [38.1K]

Answer:

* energy is proportional to masses. in a graph it would look like a line

* kinetic energy varies with the square of the velocity, In a graph it gives rise to a quadratic curve

Explanation:

Kinetic energy is defined by

        K = ½ m v²

when analyzing this expression we can see:

* energy is proportional to masses. Therefore, doubling the mass doubles the kinetic energy and if the mass rises 4 times the energy rises 4 times, that is, they are directly proportional, in a graph it would look like a line

* kinetic energy varies with the square of the velocity. Therefore by doubling the speed the energy goes up 4 times. In a graph it gives rise to a quadratic curve
