A skateboarder is accelerating forward. How would his acceleration change if he had more mass?

Physics
1 answer:
exis [7]4 years ago
4 0

Answer:

If the force remains the same, the acceleration would decrease

Explanation:

According to Newton's second law, the acceleration of an object is given by

a=\frac{F}{m}

where

F is the force applied to the object

m is the mass of the object

As we see from the formula, the acceleration a is inversely proportional to the mass, m. Therefore, if the force F remains constant, this means that if the mass of the skateboarder increases, then the acceleration will decrease.

Suppose that a spiral galaxy is located at the center of a spherically symmetric dark matter halo
Novosadov [1.4K]

To solve the problem it is necessary to use the concepts of Orbital Speed considering its density, and its angular displacement.

In general terms the Orbital speed is described as,

V_{orbit} = \sqrt{\frac{G\rho 4\pi r^3}{3}}

PART A) If the orbital speed of a star in this galaxy is constant at any radius, then,

\frac{4\pi G\rho r}{3} = \frac{v^2}{r}

\frac{4\pi G\rho r}{1} = \frac{3v^2}{r}

\frac{\rho}{1} = \frac{3v^2}{r^2 4\pi G}

\rho = \frac{1}{r^2}

PART B) This time we havev=\omega t, where \omega is the angular velocity (constant at this case)

\frac{4\pi G\rho r}{3} = \frac{v^2}{r}

\frac{4\pi G\rho r}{3} = \frac{(\omega r)^2}{r}

\rho = \frac{3\omega r}{4\pi Gr}

\rho = \frac{3\omega^2}{4\pi G} \propto constant

PART C) If the total mass interior to any radius r is a constant,

\frac{4\pi G\rho r}{3} = \frac{v^2}{r}

\frac{GM}{r^2}=\frac{v^2}{r}

v = \sqrt{\frac{GM}{r}}

v= \sqrt{\frac{1}{r}}

The wave speed on a string under tension is 200 m/s. What is the speed if the tension is doubled?
Maksim231197 [3]

Answer:

v = 282.84 m / s

Explanation:

The speed of a wave in a wire is given by the equation

       .v = √ T /ρ

Where v is the speed of the wave, T the tension in the wire and ρ the density of the wire

 If the tension is doubled

        T = 2T₀

        v = √ (2T₀ / ρ)

        v = √2   √ T₀ / ρ

        v = √2  v₀

calculate

       v = √2  200

       v = 282.84 m / s
