if a smooth ball is 39.5mm and mass is 23g, the ball is released from underwater....
A ball of mass m and another ball of mass 3m are placed inside a smooth metal tube with a massless spring compressed between them. When the spring is released, the heavier ball flies out of one end of the tube with speed v0. With what speed does the lighter ball emerge from the other end? Express your answer in terms of v0 just vo v=
13. A ball of mass 0.2 gram with radius 0.8cm is completely submerged underwater and held there. (a) Determine the buoyant force on the ball (b) the acceleration of the ball the moment it is released. [Hint: see the examples that were emailed to you]
15. A ball of mass m moves inside the smooth pipe with a constant relative velocity w. The pipe is attached to the plate at the distance h from its axis of rotation with the constant angular velocity Neglecting the gravity acceleration, determine the reaction R of the pipe on the ball, if the ball is at the position determined by the angle a= n/4

2. A small box of mass m is kept on a fixed, smooth sphere of radius R at a position where the radius through the box makes an angle of 30° with the vertical. The box is released from the position. (a) What is the force exerted by the sphere on the box just after the release? (b) Find the distance travelled by the box before it leaves contact with the sphere. 3. A particle is suspended from a fixed...
Determine the wavelength of light emitted in nanometers for an electron with a mass of 9.109383x10-23g and a velocity of 1.9x108 cm/s?
the block is released from rest. the vertical rod is
smooth.. determine its velocity after the block falls H. underfomed

Ball, with mass m, released from rest at a height y,o- Air resistance is found to be FD-KV2. (a) Find the Eulerian description of this velocity field. (2006) (b) Find the acceleration for this velocity field. (20%) mg
An object of mass 0.04kg is released from rest at the lip of a smooth hemispherical bowl of radius R. The object slips down the side and collides with another object of mass 0.1 kg sitting at the bottom of the bowl. You can ignore friction between the masses and the surface of the bowl. If they stick together when they collide, how high above the bottom of the bowl will the masses go after colliding?
a spherical ball hangs on a string on a smooth, frictionless wall.The mass of the ball is m,its radius is R,and the length of the string is l. Draw a “free-body”diagram with all the forces acting on the ball.Find the normal force between the ball and the wall.Show that N goes to 0 as l goes to infinity. Solve for T and check your answer in this limit as well as in the limit specified in the problem statement.
