Potential energy is the energy that is possible to be realized, based on position, while  the kinetic energy is the energy that is present and due to motion

The location where the potential energy is converted into kinetic energy is the point (2)

Reason:

The mechanical energy, M.E., of the roller coaster, is given as follows;

M.E. = P.E. + K.E.

Where;

P.E. = The potential energy = m·g·h

K.E. = The kinetic energy = \dfrac{1}{2} \cdot m \cdot v^2

Where;

v = The velocity

h = The height

m = The mass

g = Acceleration due to gravity

∴ M.E. = m·g·h + \dfrac{1}{2} \cdot m \cdot v^2

The mechanical energy, M.E., is constant, therefore;

When the height, h = 0, we have, the kinetic energy is maximum, given that the mechanical energy is entirely kinetic energy

Therefore;

The locations where potential energy is converted to kinetic energy are lowest locations, where the height, <em>h</em>, is minimum, such as the point (2)

What does the potential energy and kinetic energy of an object depend on ?
alexdok [17]

Answer:

Both, potential energy and kinetic energy depends on mass. The higher the mass, the higher the energy. However, the difference is that potential energy depends on vertical height whereas kinetic energy depends on the velocity.

Explanation:

From the formula we can see that;

Potential Energy = mass* gravitational acceleration *vertical height.

Kinetic Energy = 0.5 * mass * (velocity)^2

The position of an electron is given by , with t in seconds and in meters. At t = 3.99 s, what are (a) the x-component, (b) the
egoroff_w [7]

Answer:

A. Vx = 3.63 m/s

B. Vy = -45.73 m/s

C. |V| = 45.87 m/s

D. θ = -85.46°

Explanation:

Given that position, r, is given as:

r = 3.63tˆi − 5.73t^2ˆj + 8.16ˆk

Velocity is the derivative of position, r:

V = dr/dt = 3.63 - 11.46t^j

A. x component of velocity, Vx = 3.63 m/s

B. y component of velocity, Vy = -11.46t

t = 3.99 secs,

Vy = - 11.46 * 3.99 = -45.73 m/s

C. Magnitude of velocity, |V| = √[(-45.73)² + 3.63²]

|V| = √(2091.2329 + 13.1769)

|V| = √(2104.4098)

|V| = 45.87 m/s

D. Angle of the velocity relative to the x axis, θ is given as:

tanθ = Vy/Vx

tanθ = -45.73/3.63

tanθ = -12.6

θ = -85.46°

A uniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weigh
dem82 [27]

Answer:

Explanation:

a )

Reaction force of the ground

R = mg

= 160 N

Maximum friction force possible

= μ x R

= μ x 160

= .4 x 160

= 64 N .

b )

 160 N will act at middle point . 740N will act at distance of 3 / 5 m from the wall ,

Taking moment about top point of ladder

160 x 1.5 + 740 x 3/5 + f x 4 = 900 x 3

240 + 444 + 4f = 2700

f = 504 N

c )

Let x be the required distance.  

Taking moment about top point of ladder

160 x 1.5 + 740 x 3 x / 5 + .4 x 900 x 4  = 900 x 3  ( .4 x 900 is the maximum friction possible )

240 + 444 x + 1440  = 2700

x = 2.3  m

so man can go upto 2.3 at which maximum friction acts .
