The force exerted by Earth plays the role of centripetal force.
The angle theta of the spring is 31 degrees. To solve for this, show the equation which is equal to the 10lb ball. With this, the unknown will be the angle. Then transpose/transfer the terms in order to isolate the variable for the angle. First solve for s, then solve for angle theta. You will come up with s = .5849 ft and angle theta = 31.2629 or 31 degrees. Hope this helps.
The answer would be Inertia. Inertia is the tendency for an object to stay at its state of motion. Newton's 2nd law states that that an object in motion tends to stay in motion unless an external force acts upon it.
Answer:
Explanation:
= Initial diameter = 4 cm
= Initial velocity = 1 m/s
= Final diameter = 7.8 m
= Final velocity
= Area =
From the continuity equation we get
The speed of water at the second floor is .
