How much force would be needed to push the ball completely under water?(answer in N)
Homework Answers
force needed to push the ball completely under water
F = ρF* Vdispl* g
ρF= 1000 kg/m^3
d = 56-cm = .56 m
g = 9.8 m/s^2
Vdispl= (4/3)π * (d/2)^3 = (1/6)π *d^3
Vdispl = (4/3)π * (.56/2)^3 = .09195
F = 1000*.09195*9.8
F = 901.11 N

A child playing in a swimming pool realizes that it is easy to push a small inflated ball under the surface of the water whereas a large ball requires a lot of force. The child happens to have a styrofoam ball (the shape of the ball will not distort when it is forced under the surface), which he forces under the surface of the water. If the child needs to supply 635 N to totally submerge the ball, calculate the...

3. If you've ever played with an inflated ball of any type while swimming, you've probably noticed that if a ball is already floating on the surface of the water, it's easy to push it down a few centimeters. But then it's harder to push it the next few cm down, and so on, until the ball is completely submerged-the last few cm are the hardest! submerged. 1-2 sentences, no equations or math. b) Suppose, once the ball is completely...
