A solid disk of radius 5.50 cm and mass 1.25 kg , which is rolling at a speed of 1.50 m/s , begins rolling without slipping up a
shtirl [24]

Answer:

Explanation:

Deceleration of solid disk = g sin10/1 + k²/r² = g sin 10 / 1 + 1/2 = g sin 10 x 2/3

[ k is radius of gyration of disk which is equal to( 1/√2)x r ]

deceleration a = -1.1345 m/s²

v = u - at , t = u / a = 1.5 / 1.1345 = 1.322 s.

The potential energy of a particle experiencing a certain kind of force is given by U(x) = 2x + 8 x measured in joules (J), for
masha68 [24]

Answer:

Explanation:

Given

Potential Energy of a particle is given by U(x)=2x+\frac{8}{x}

For minimum or maximum Potential Energy differentiate U(x) w.r.t x

\frac{\mathrm{d} U}{\mathrm{d} x}=2-\frac{8}{x^2}

putting \frac{\mathrm{d} }{\mathrm{d} x}=0

2-\frac{8}{x^2}=0

x^2=\frac{8}{2}

x^2=4

x=\sqrt{4}=\pm 2

To know minimum value check \frac{\mathrm{d^2} U}{\mathrm{d} x^2}

at x=-2

\frac{\mathrm{d^2} U}{\mathrm{d} x^2}=\frac{16}{x^3}=-\frac{16}{8}=-2

so at x=-2 potential energy is minimum U=-8\ J
