Velocity is defined as the displacement over time. In the diagram, we can solve velocity by taking the two distances over time. 
Velocity = (D1-D2)/(t1-t2)
where
D1=5m D2=10m, t1=0s, t2=2s
Velocity= 10m-5m/(2s-0s)
Velocity = 2.5m/s

Daniela's velocity is equal to 2.5m/s.

How would you set up SMART goals for your clients?​
aleksklad [387]

Answer: The client must be advised while preparing a goal either for a treatment or for a fitness class.

Explanation:

The client goal must be set in a way that it should be measurable, attainable, time-bound.

The measurable goal is the in the sense that the client can measure own success.

The attainable is in the sense  the client can achieve and perform all set plans in the goal.

Time-bound is in the sense that the client can devote sufficient time to obtain success.

. Suppose an electron is chasing a proton up this page when suddenly a magnetic field pointing into the page is applied. What wo
irina1246 [14]

The proton and electron experience forces to the left and right of the page, the particles would separate to the left and right respectively after the magnetic field is applied.

To know what would happen to each particle when a magnetic field pointing in the direction of the page is applied, we need to know the direction of the force acting on the particles due to this magnetic field according to fleming's left hand rule

<h3>What is Fleming's left hand rule?</h3>

This states that when the thumb, the middle-finger and fore-finger of the left-hand are held at right angles to each other, the magnetic field points in the direction of the fore-finger, the current (or direction of charge) points in the direction of the middle finger and the force on the conductor or charge points in the direction of the thumb.

<h3>What is the direction of force on the proton?</h3>

Since the direction of the proton is up the page and the direction of the magnetic field is into the page, the direction of the force according to fleming's left hand rule is to the left of the page.

<h3>What is the direction of force on the electron?</h3>

Since the direction of the electron is up the page (it is in the direction of the conventional current or positive charge in the other direction) and the direction of the magnetic field is into the page, the direction of the force according to fleming's left hand rule is to the right of the page.

Since both the proton and electron experience forces to the left and right of the page, the particles would separate to the left and right respectively after the magnetic field is applied.

Josh starts his sled at the top of a 2.9-m-high hill that has a constant slope of 25∘. After reaching the bottom, he slides acro
algol13

Answer:

S=48.29 m

Explanation:

Given that the height of the hill h = 2.9 m

Coefficient of kinetic friction between his sled and the snow μ = 0.08

Let u be the speed of the skier at the bottom of the hill.

By applying conservation of energy at the top and bottom of the inclined plane we get.

Potential Energy=kinetic Energy

mgh = (1/2) mu²

u² = 2gh

u²=2(9.81)(2.9)

   =56.89

u=7.54 m/s

a = - f / m

a = - μ*m*g / m

a = - μg

From equation of motion

v²- u² = 2 -μ g S

v=0 m/s

-(7.54)²=-2(0.06)(9.81)S

S=48.29 m
