You are designing a diving bell to withstand the pressure of seawater at a depth of 260m .
What is the gauge pressure at this depth? (You can ignore changes in the density of the water with depth.)
At this depth, what is the net force due to the water outside and the air inside the bell on a circular glass window 34.0cm in diameter if the pressure inside the diving bell equals the pressure at the surface of the water? (You can ignore the small variation of pressure over the surface of the window.)
A banked circular highway curve is designed for traffic moving at 77-km/h. The radius of the curve is 153 m. Traffic is moving along the highway at 46-km/h on a rainy day. What is the minimum coefficient of friction between tires and road that wil..

An apple is dropped from a 25m cliff. At the similar time, a person at the bottom of the cliff fries an arrow up towards the apple. The arrow sticks the apple 0.450 seconds later.
A golf ball strikes a hard, smooth floor at an angle of 33.1 ° and, as the drawing shows, rebounds at the same angle. find the magnitude of the impulse applied to the golf ball by the floor
1.7 kilograms of water are changed from ice at 0?C into liquid water at 0?C, determine the change in mass of the water
Four 8.5 kg spheres are located at the corners of a square of side 0.80 m. Calculate the magnitude and direction of the total gravitational force
the magnitude of the net electric field. A lead ball is dropped into a lake from a diving board 6.40 above the water. After entering the water, it sinks to the bottom with a constant velocity equal to the velocity with which it hit the water.
A 1.0 kg stone is being whirles at constant speed of 12 m/s in a circle, held on a frictionless surface by a steel wire which is horizontal. The wire is 4.0 m long and its radius is 1.0 mm. Find out the strain in the wire.
A ball swings in a vertical circle at the end of a rope 1.40 m long. When the ball is 35.5° past the lowest point on its way up, Determine the magnitude of its radial acceleration
