A ball is tossed with sufficient speed straight up so that it is in the air several seconds. a) What is the velocity of the ball when it reaches its highest point? b) What is its velocity 1s before it reaches its highest point? c) What is the change in its velocity through this 1-s interval? d) What is its velocity 1s after it reaches its highest point? e) What is the change in velocity through this 1-s interval? f) What is the change in velocity during the 2-s interval? g) What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?
A 50 kg rider on a moped of mass 75 kg is traveling with a speed of 20m/s. Each of the two wheels of the moped has a radius of0.2m and a moment of inertia of 0.2 kg*m^2. What is the total rotational kinetic energy of the wheels?
If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball? (Suppose right is the positive direction.)
A point charge of -12 micro-coulombs is fired directly towards a single infinite sheet of charge. It is initially moving at 3.4 m/s towards the sheet and after it has traveled 0.7 meters it is moving at 18.4 m/s.
You are asked to make some measurements of microwaves using a "polarizing grid" consisting of metal wires.Since an electric field does not penetrate a conductor, linearly polarized microwave radiation will pass through the grid most easily when (m..
What is the wavelength of light for the least energetic photon emitted in the Balmer series of the hydrogen atom spectrum lines
In a single-slit diffraction pattern on a flat screen, the central bright fringe is 1.7 cm wide when the slit width is 3.9 x10-5 m. When the slit is replaced with a second slit, the wavelength of the light and the distance to the screen remaining unc..
