Answer:
d = 19.796m
Explanation:
Since the ball is in the air for 4.02 seconds, the ball should reach the maximum point from the ground in half the total time, therefore, t=2.01s to reach maximum height. At the maximum height, the velocity in the y-direction is 0.
So we know t=2.01, vi=0, g=a=9.8m/s and we are solving for d.
Next, you look for a kinematic equation that has these parameters and the one you should choose is:
Now by substituting values in, we get
d = 19.796m
<u>The Weight </u>is a vector whose magnitude is the product of the mass m of the object and the magnitude of the local gravitational acceleration. Its always directed toward the center of the Earth.
Its average speed, pretending that it traveled at a constant speed, is
v = s / t
= 600 m
5 x 60 s
= 2 m/s
but to be a velocity it needs a direction as well as a speed.
( Sorry. Can’t find a division line to put between the 600 m and the 5 x 60 s )
Answer:
42.58kg
Explanation:
By Newton's second law, F = ma.
F is the force being applied, in this case 112N. a is the acceleration, in this case 2.63 m/s^2.
Thus, with some simple algebraic manipulation, we get the mass to equal:
m = F/a = 112N / 2.63 m/s^2 = 42.58kg
One of the most important aspects of civilization is communication.
People need one another, and in order for them to communicate and understand one another, they must be able to understand one another. The communication cycle explains how the mechanism of message transmission and comprehension works.
Although different cycles may have slightly varied phases and descriptions, the fundamental components are often the same:
Sender: the sender of communication is a person or an organization.
Message: The details the sender wants to share
Encoding is the process the sender uses to transform the message into one that can be sent.
The channel is the method used to send the message.
recipient: the individual or thing to whom the communication is
Decoding: How the communication is interpreted and comprehended by the recipient
Feedback: the reaction of the recipient
