Answer:
The workdone by Jack is
The workdone by Jill is
The final velocity is
Explanation:
From the question we are given that
The mass of the boat is
The initial position of the boat is
The Final position of the boat is
The Force exerted by Jack
The Force exerted by Jill
Now to obtain the displacement made we are to subtract the final position from the initial position
Now that we have obtained the displacement we can obtain the Workdone
which is mathematically represented as
The amount of workdone by jack would be
The amount of workdone by Jill would be
According to work energy theorem the Workdone is equal to the kinetic energy of the boat
Answer:
The answer to your question is the letter D. 2.5 N
Explanation:
The electrostatic force is the same in both directions,
If the electrostatic force on B due to A is 2.5 N, the magnitude of the electrostatic force on A due to B must be 2.5N.
Maybe the direction is different but the magnitude is the same.
Answer:
Shape of the object
Explanation:
This depends on the shape of the object. For a spherical object, a unitless value of 0.47 is typical. The magnitude of the velocity squared. The faster you go, the greater the air resistance force
The x and y coordinates of the particle at this moment is (6x + 4.5y) m.
<h3>
Position of the particle </h3>
The position of the particle at any instant is determined from the velocity and acceleration of the particle as shown below.
v² = u² + 2as
where;
- v is the final velocity of the particle
- u is the initial velocity
- a is the acceleration of the particle
- s is the position of the particle
v² = 0 + 2as
v² = 2as
s = v²/2a
<h3>X and y - coordinates of the particle</h3>
Thus, the x and y coordinates of the particle at this moment is (6x + 4.5y) m.
