<span>The centripetal force for such an arrangement can be found through the equation Fc = mv^2/r where m is the mass of the rotating object, v is that object's velocity, and r is the radius of rotation. In this case, we know that the maximum Fc that can be tolerated by the cord is 64N. Thus we set the equation up and solve for the value of v for which Fc = 64.
64 = 0.4*(v^2)/1
64/0.4 = 160 =
v^2
v = sqrt(160) = 12.65 m/s
At any speed faster than 12.65 m/s, the cord will break.</span>
The horizontal component of velocity is
(22 m/s) • cosine(62°).
The vertical component of velocity is
(22 m/s) • sine(62°).
These are the original components, right after the kick. As time goes on, the horizontal one doesn't change. But the vertical one gets bigger and bigger, because gravity is accelerating the ball downward.
That's the complete story of projectile motion.
Answer:
I would say that your best answer would be C.
I'm not too sure about this, but it's the best answer on there
Explanation:
Hope this helps you.
Answer:
Low.
Explanation:
If you are performing an activity close to the ground, then that means that you are performing at a low level.
