Consider a uniform solid sphere of radius R and mass M rolling without slipping. The moment of inertia of the sphere about an ax

is through its center is 25MR2. Which form of its kinetic energy is larger, translational or rotational? Consider
Physics

Lerok [7]3 years ago
8 0

Explanation:

Its translational kinetic energy is:

KE = ½ mv²

It's rotational kinetic energy is:

RE = ½ Iω²

For a solid sphere, I = ⅖ mr², and since it's not slipping, ω = v/r.

RE = ½ (⅖ mr²) (v/r)²

RE = ⅕ mv²

Therefore, the translational kinetic energy is larger.

An ideal horizontal spring-mass system has a mass of 1.0 kg and a spring with constant 78 N/m. It oscillates with a period of 0.
steposvetlana [31]

Answer:

T = 0.71 seconds

Explanation:

Given data:

mass m = 1Kg, spring constant K = 78 N/m, time period of oscillation T = 0.71 seconds.

We have to calculate time period when this same spring-mass system oscillates vertically.

As we know

T = 2\pi \sqrt{\frac{m}{K} }

This relation of time period is true under every orientation of the spring-mass system, whether horizontal, vertical, angled or inclined. Therefore, time period of the same spring-mass system oscillating  vertically too remains the same.

Therefore, T = 0.71 seconds
