At any angular speed, a certain uniform solid sphere of diameter D has half as much rotational kinetic energy as a certain unifo

Trava [24]

Answer:

d. 6/5 M.

Explanation:

let the angular velocity = $\omega$

the radius of sphere (r) = $\frac{D}{2}$

moment of inertia of solid sphere $I_s$ = $2/5 M(\frac{D}{2})^2$

rotational K.E of solid sphere= $\frac{1}{2}* I_s* \omega ^2$

= $\frac{1}{2} * 2/5 M(\frac{D}{2})^2 * \omega^2$

we represent the mass of hallow sphere= $M_{hs}$

moment of inertia of solid sphere $I_{ss}$ = $2/3 M_{hs}(\frac{D}{2})^2$

rotational K.E of hollow sphere= $\frac{1}{2}* I_{ss} * \omega^2$

= $1/2 *2/3 M_{hs}(\frac{D}{2})^2* \omega^2$

NOW,the kinetic energy of solid sphere= 1/2 kinetic energy of hallow sphere

= $1/2 [2/5 M(D/2)^2 ]\omega^2= 1/2 (1/2 (2/3 M_{hs}(D/2)^2 )\omega^2 }$

2/5M= 1/3 $M_{hs}$

$M_{hs}$ = 3(2/5M)

$M_{hs}$ = 6/5 M

A 5.5 kg box is pushed across the lunch table. The acceleration of the box is 4.2 m/s2. What was the net force applied to the bo

Bezzdna [24]

Use this numbers that you are given and plug them into the formule for net force

Net force= m*a (mass times acceleration)

Therefore the net force is equal to (5.5 kg)*(4.2 m/s^2)= 23.1 N

Answer: Net force= 23.1 N
