There doesn't seem to be any direct connection.
Answer:
The displacement is
The distance is
Explanation:
From the question we are told that
The height from which the ball is dropped is
The height attained at the first bounce is
The height attained at the second bounce is
The height attained at the third bounce is
Note : When calculating displacement we consider the direction of motion
Generally given that upward is positive the total displacement of the ball is mathematically represented as
Here the 0 show that there was no bounce back to the point where Billy released the ball
=>
Generally the distance covered by the ball is mathematically represented as
The 2 shows that the ball traveled the height two times
=>
Question
Assume mass of Ashley as 60 kg and Miranda 70 kg
Answer:
3.56 m/s
Explanation:
From law of conservation of linear momentum, the sum of initial momentum equals the sum of final momentum.
Momentum, p=mv where m is mass and v is velocity. In this case
M1v1+m2v2=(m1+m2)v where v is common velocity in question.
60*2+70*4.9=(60+70)v
V=3.56 m/s
Answer: The force needed is 140.22 Newtons.
Explanation:
The key assumption in this problem is that the acceleration is constant along the path of the barrel bringing the pellet from velocity 0 to 155 m/s. This means the velocity is linearly increasing in time.
The force exerted on the pellet is
F = m a
In order to calculate the acceleration, given the displacement d,
we will need to determine the time t it took for the pellet to make the distance through the barrel of 0.6m. That time can be determined using the average velocity of the pellet while traveling through the barrel. Since the velocity is a linear function of time, as mentioned above, the average is easy to calculate as:
This value can be used to determine the time for the pellet through the barrel:
Finally, we can use the above to calculate the force:
Answer:
Inductance as calculated is 13.12 mH
Solution:
As per the question:
Length of the coil, l = 12 cm = 0.12 m
Diameter, d = 1.7 cm = 0.017 m
No. of turns, N = 235
Now,
Area of cross-section of the wire, A =
We know that the inductance of the coil is given by the formula:
