What is a free body diagram?
Answer: a force diagram is a graphical illustration used to visualize the applied forces and resulting reactions on a body in a given condition
Drawing a free-body diagram for this problem
Answer: Look at the attached picture, ask me any questions if you are still confused. It is a little messy since I didn't have my pen.
Find its weight on Earth
Answer: The weight is dependent on the mass of the object and the gravitational constant on the planet. The gravitational constant, in this case, is 9.8.
so the weight = mass * gravitational constant = m * g = 1000 * 9.8
= 9800 N
Hope that helps!
Answer:
left hand: 133 N upward
right hand: 83N downward
Explanation:
10 cm = 0.1m
Let g = 10m/s2. The pole gravity force would be
. Suppose the pole mass distribution is uniform, this means the center of mass is at its geometric center, aka 5/2 = 2.5m from the top end.
In order for the system to stay balanced, the total net force and net moment must be 0
where
are the forces exerted by his left and right hand, respectively.
We will pick his right hand (0.1 m from the top end) as moment pivot point. The total moment generated by pole gravity and his left hand must be 0
Distance (or moment arm length) from pole center to his right hand is
Moment generated by gravity around his right hand is:
counter-clockwise
Distance (or moment arm length) from left hand to his right hand is
Moment generated by force from his left hand around his right hand is:
clockwise
Since the total moment must be 0, the clockwised-direction moment = counterclockwised-direction moment:
upward
Therefore, the force exerted by his right hand must be 50 – 133 = -83 N or 83N downward
D = 318 meters
vi = 0 m/s
vf =????
a = 9.81
Formula
=======
vf^2 = vi^2 + 2*a*d
Substitute and solve.
================
vf^2 = 0^2 + 2 * 9.81 * 318
vf^2 = 6239.16
v = sqrt(6239.16)
v = 78.990 m/s I guess down is minus in your classroom.
Anyway pick -79 <<<<<=======
A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation, which are represented in the given function as 6 units and 98 rad/s respectively.
<h3>General wave equation for simple harmonic motion</h3>
y = A sinωt
where;
- A is amplitude of the motion
- ω is angular frequency
<h3>Amplitude of the oscillation</h3>
A = 6 units
<h3>Angular frequency of the wave</h3>
ω = 98 rad/s
A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation. Thus, the wave is executing simple harmonic motion.
