Find the change in velocity of a 369 g hockey puck subject to the force shown below.

Elena-2011 [213]

Answer:

The change in velocity is 15.83 [m/s]

Explanation:

Using the Newton's second law we have:

ΣF = m*a

The force in the graph is 185 N, therefore:

$185=0.369*a\\Where\\a=acceleration made it by the force [m/s^2]$

$a=501.35[m/s^2]$

Now using the following kinematic equation:

$V^{2}=Vi^{2} + 2*a*(x-xi) \\where\\V=final velocity [m/s]\\Vi= initial velocity [m/s] = 0 the hockey disk is in rest when receives the hit.\\ x = Final position [m] = 0.4 m\\xi = initial position [m] = 0.15m\\$

Now replacing the values:

$V^{2}=0 + 2*501.35*(0.4-0.15)\\ \\V= 15.83[m/s]$

Help needed Can a body be accelerating if it is moving in circle

belka [17]

Answer:

When a body is moving on a circle it is accelerating because centripetal acceleration is always acting on it towards the center.

Please see the attached picture...

From the above diagram,we can say the acceleration is always acting on the body when it moves in a circle.

Hope this helps.......

Good luck on your assignment.......

Electromagnetic radiation consists of discrete packets of kinetic energy called Photons, which are characterized by a certain wavelength and energy level.

<h3>What are photons? </h3>

The representation by a particle of a quantum of light or any other electromagnetic radiation is called photons. The energy is proportional to the frequency of radiation however it has zero mass. It travels at a constant speed. It is a carrier of energy. When the sun changes the particles into both light and heat, it is a photon. They don’t carry any electrical charge. They are like electric fields traveling through space as shown by Maxwell in his theory. They can be easily created and destroyed. They are also called light quantum.
