A particle moving along the x-axis has a position given by x = (24t – 2.0t 3 ) m, where t is measured in s. What is the magnitud
Vitek1552 [10]
<h2>The magnitude 24 (\dfrac{m}{s^2} ) of the acceleration of the particle when the particle is not moving.</h2>

Explanation:

Given,

A particle moving along the x-axis has a position given by

x=(24t-2.0t^3) m      ........ (1)

To find, the magnitude (\dfrac{m}{s^2} ) of the acceleration of the particle when the particle is not moving = ?

Differentiating equation (1) w.r.t, 't', we get

\dfrac{dx}{dt} =\dfrac{d((24t-2.0t^3))}{dt}

⇒ \dfrac{dx}{dt} =24(1)-3(2.0)t^{2} =24-6t^{2}     ....... (2)

⇒ 24-6t^{2} = 0

⇒ t^{2}=2^{2}

⇒ t = 2 s

Again, differentiating equation (2) w.r.t, 't', we get

\dfrac{d^2x}{dt^2} =-12t

Put t = 2, we get

\dfrac{d^2x}{dt^2} =-12(2)=24

Thus, the magnitude 24 (\dfrac{m}{s^2} ) of the acceleration of the particle when the particle is not moving.

A car starts at the top of a hill with 200 J of energy, and rolls down a frictionless surface. The isolated system consists of t
Kamila [148]

Answer:

The total energy stays the same but is converted from being stored as gravitational potential energy into kinetic energy of the car as it moves.

Explanation:

the law of conservation of energy states that the total energy of an isolated system remains constant, and since it is gaining speed that energy will be kinetic

A person pushes a 50kg box to the right with 100N of force at a constant velocity of 5m/s. Calculate the coefficient of friction
Anna11 [10]
The weight of the box is 50x9.8 = 490 N. The force of friction is 100N. F= μΝ so coefficient = 100/490 = 0.20
