What is the tangential speed of a point on a wheel of a car if the point is located 0.114 m from the axis of rotation; and the w

heel is rotating at 6.53 rev/sec?

Svetach [21]2 years ago

Answer:

Tangential speed = R * w  where w is the angular speed

For a wheel   v = .114 m * 6.53 / sec = .744 m/s

Note that this is the tangential speed - If the wheel were moving at speed V then as viewed from the ground you have

top V + v

bottom   V - v

That is the wheel also has speed due to the speed of the axle (axis of rotation)

A skater slides across the ice with an initial velocity of 5.0 m/s. She slows 10 points
zvonat [6]

Explanation:

Given that,

The initial velocity of a skater is, u = 5 m/s

She slows to a velocity of 2 m/s over a distance of 20 m.

We can find the acceleration of skater. It is equal to the rate of change of velocity. So, it can be calculated using third equation of motion as follows :

v^2-u^2=2as

a = acceleration

a=\dfrac{v^2-u^2}{2s}\\\\a=\dfrac{(2)^2-(5)^2}{2\times 20}\\\\a=-0.525\ m/s^2

So, her acceleration is 0.525\ m/s^2 and she is deaccelerating. Also, her initial velocity is given i.e. 5 m/s.

Which of the following best describes the term thermal energy? Choose one: A. The energy of an object in motion due to its mass
o-na [289]

Answer:

The correct option is (d).

Explanation:

  • The energy a particle has because of its charge and its position relative to another particle is called thermal energy.
  • It is the energy that comes from heat. This is generated by the movement of the particles in an object.
  • Thermal energy is the energy an object or system has due to the movement of particles within.

Hence, the correct option is (d).
