Answer:
Minimum speed will be equal to 2.213 m/sec
Explanation:
We have given radius of the r = 2 m
Coefficient of friction
At minimum speed frictional force will be equal to centripetal force
So
So the minimum speed will be equal to 2.213 m/sec
Protons, electrons, and neutrons have electrical charges. Protons are positive. Electrons are negative and neutrons are neutral (no charge).<span />
We study the movement of each body separately. For the mass body A: vector: T + Na + Ga + Ff = ma * a.Scalar: on the axis Ox: ma * g * sinα-T-Ff = ma * a
On the axis Oy: Na-ma * gcosα = 0=>Na=ma * g*cosα
Ff=μ*N=μ*ma * g*cosα
ma * g * sinα-T-μ*ma * g*cosα=ma*a
For mass body B: vector: Gb + T = mb * a.Scalar: by projection of the vector relation on the axis Ox:T-mb*g=mb*a
