If I'm correct if you pluck the center of the string creating a pulse off both directions and would be reflected off the ends of the string my calculations would be 10.37sec
Answer:
F = 35651 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces is equal to the product of mass by acceleration.
But first, we must use the following equation of kinematics to find acceleration.
where:
Vf = final velocity = 185 [m/s]
Vi = initial velocity = 0 (the cannon ball is at rest in the first moment)
a = acceleration [m/s²]
x = distance = 3.6 [m]
Now replacing these values into the equation:
(185)² = 0² + (2*a*3.6)
34225 = 7.2*a
a = 34225/7.2
a = 4753.5 [m/s²]
Now using Newton's second law we have:
F = m*a
where:
F = force [N]
m = mass = 7.5 [kg]
F = 7.5*4753.5
F = 35651 [N]
Answer:
<h2>320</h2>
Just use F =ma where m is mass and a is acc.
Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl.
Answer:
This is because using a long handled requires less force to the center of gravity and makes it easier to rotate than a short handled spanner
