Coefficient of kinetic friction </h3>
The coefficient of kinetic friction between the base runner and the ground is calculated as follows;
μ = a/g
where;
- a is acceleration
- g is gravity
v² = u² + 2as
a = (v² - u²)/(2s)
a = (8.451² - 2.322²)/(2 x 6.596)
a = 5 m/s²
μ = 5/9.8
μ = 0.51
Thus, the coefficient of kinetic friction between the baserunner and the ground is 0.51.

A) Net force in component form: 
B) Magnitude of the net force: 316.2, direction: 
Explanation:
A)
The three forces given in this problem are:



The three forces are given in component form, where the components with unit vector i is the component along the x-direction, while the components with unit vector j is the component along the y-direction.
In order to find the net force in component form, we just need to add the components of the three forces along each direction. Therefore:
- Along the x-direction:

- Along the y-direction:

So, the net force in component form is

B)
The magnitude of a vector F is given by Pythagorean's theorem:

where in this problem,
is the x-component
is the y-component
Substituting,

The direction instead is given by

where the negative sign means the direction is below the positive x-axis.

Answer:F=0.0882kg
Explanation:
The period it takes to make one revolution is 1.5 seconds / revolutions,
v = r * (change in angle / change in time)
the change in angle is 2pi, for one whole revolution. the time is 1.5 second per revolution, and the radius is 0.1.
v = (2 * pi * 0.1 cm * / 1.5second
v = 0.42m/s
a=v^2/r
a=0.42^2 /0.1 =1.764m/s2
F=ma
F=0.05*1.764
F=0.0882kg
Answer:
<h2>8.78 Amps</h2>
Explanation:
Given data:
power rating of the heater P= 1010 W
voltage of the heater V= 115 volts
current taken by the heater I= ?
We can apply the power formula to solve for the current in the heater
i.e P= IV
Making I the current subject of formula we have
I= P/V
Substituting our given data into the expression for I we have
I=1010/115= 8.78 A
<h2 /><h2><em>Hence the current when the unit/heater is operating is 8.78 Amp</em></h2>
