The last equation gives you the tension in the string on the right:
In physics<span>, a </span>force<span> is said to do </span>work<span> if, when acting, there is a </span>displacement<span> of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement).
power= work over time
the more power you put into your work the less time it will take, if you have less power the more time</span>
Answer:
Explanation:
Given that the angular velocity is constant.
The actual weight is W = 549N
The ride apparent weight is
W' = 1.5N
Apparent weight at the top of the ride?
Using newton second law of motion
ΣF = m•ar
ar is the radial acceleration
N — W = —m•ar
N = W —m•ar
N = mg —m•ar
N = m(g—ar)
The apparent weight is equal to the normal
W'(top) = N = m(g—ar)
W'(top) = m(g—ar)
W'(top) = mg —m•ar
We know that the actual weight is
W=mg
Also, the apparent weight is
W' = m•ar
Then
W'(top) = Actual weight - apparent
W'(top) = 549—1.5
W'(top) = 547.5 N
