You and your friends are playing in the swimming pool with a 40-cm-diameter beach ball. How much force would be needed to push the ball completely under water?
You and your friends are playing in the swimming pool with a 56-cm-diameter beach ball. How much force would be needed to push the ball completely under water?(answer in N)
please help!!! A child playing in a swimming pool realizes that it is easy to pash a small inflated ball under the surface of the water whereas large ball requires a lot of force. The child happens to have a styrofoam ball (he 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 581 N to totally submerge the ball,calculate the...
what downward force is required to keep a ball of weight 1.30 n and radius 4 cm submerged in water?
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...
A rubber ball filled with air has a diameter of 24.3 cm and a mass of 0.454 kg. What force is required to hold the ball in equilibrium immediately below the surface of water in a swimming pool?

You have a rocket of mass 2350 kg. How much work does the force of gravity do on the rocket if it moves from Earth's surface to 3.0 times the Earth's radius away? Be careful to use the definition of work that accounts for a force that changes based on location! J G = 6.67 x 10-11 m3/kg/s2 MEarth = 5.97 x 1024 kg REarth = 6.37 x 106 m What is the change in gravitational potential energy as the...
