To solve this problem we will apply the concepts related to energy conservation. Here we will understand that the potential energy accumulated on the object is equal to the work it has. Therefore the relationship that will allow us to calculate the height will be
Here,
m = mass
g = Acceleration due to gravity
h = Height
our values are,
Replacing,
Then the height is 32.83m.
Explanation:
first, find the circumference of the wheel by using the formula 2(pi)(r):
2(pi)(19) = 119.380521
divide by 25 secs
119.380521/25 = 4.77522083
round to the nearest tenth is 4.8, so the speed is 4.8mm/sec
Answer:
Explanation:
· If two forces are in the same direction, then one adds them to find the net force, which is the vector sum of these forces. However, when two forces act in opposite direction, one has to subtract the lesser force from the larger one to find the resulting force. The resultant is the direction of the larger of these two forces.
Answer:
Zero, the support force and gravitational force together equal a zero net force
