Answer:

<h3>2,321.62Joules</h3>

Explanation:

The formula for calculating workdone is expressed as;

Workdone = Force * Distance

Get the force

F = nR

n is the coefficient of friction = 0.5

R is the reaction = mg

R = 46 ( 9.8)

R = 450.8N

F = 0.5 * 450.8

F = 225.4N

Distance = 10.3m

Get the workdone

Workdone = 225.4 * 10.3

Workdone  = 2,321.62Joules

<em>Hence the amount of work done is 2,321.62Joules</em>

If a moon on jupiter has 1/8 the mass of the earth and 1/2 the earth's radius, what is the acceleration of gravity on the planet
dusya [7]

The formula we can use here is:

g = G m / r^2

where g is gravity, G is gravitational constant, m is mass, and r is radius

Since G is constant, therefore we can equate two situations:

g1 m1 / r1^2 = g2 m2 / r2^2

(10 m/s^2) r1^2 / m1 = g2 * (1/2 r1)^2 / (1/8 m1)

<span>g2 = 5 m/s^2</span>

Consider the case in which the object is between the lens and the focal point. Trace the P ray (use the label P1 for the segment
Pani-rosa [81]

Answer:

See attachment

Explanation:

The diagram attached is a sketch of rays when the object is placed between the lens and focal point. As can be seen, the image in such cases is always on the same side of lens as the object. It is formed beyond the focal point from the lens and is magnified

What is the kinetic energy of a jogger with a mass of 65.0 kg traveling at a speed of 2.5m/s
Scrat [10]

Answer:

203.1J

Explanation:

Given parameters:

Mass  = 65kg

Speed  = 2.5m/s

Unknown:

Kinetic energy of jogger  = ?

Solution:

To solve this problem, we use the kinetic energy equation:

    K.E  = \frac{1}{2} m v²  

m is the mass

v is the velocity

 Now insert  the parameters and solve;

  K.E  =  \frac{1}{2} x 65 x 2.5²   = 203.1J
