A 0.100-kilogram white ball moving with a velocity of 5 meters/second along the positive x-axis hits a stationary blue ball of the same mass. Energy is not necessarily conserved, but momentum is. After the collision, the white ball moves off at an angle of 20° with respect to the positive x-axis and at a velocity 3.5 meters/second. The blue ball moves at an angle of -35° and a velocity of 2.1 meters/second. What is the final y-momentum of the system?
Inside the tube is a uniformelectric field of 4.50*10-4 N/C pointing in negativey-direction. How far does the particle travel before hitting the tube wall.

It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at this time. Find out the angular speed of the wheel at t = 2.30 s.
Explain why heat can only be transferred from a hot object to a cold object and not the other way around.
Young's Double Slit Experiment is performed with 589 nm light and a distance of 2.00 m between the slits and the screen. The fifth interference minimum is observed 7.50 mm from the central maximum. Resolve the spacing of the slits.
An undamped oscillator has period 0 = 1.000 seconds, but I now add a little damping so that its period changes to 1 = 1.001 seconds. What is the damping factor ? By what factor would the amplitude of oscillation decrease after 10 cycles.
A 1125 kg car and a 2250-kg pickup truck approach a curve on the express way that has a radius of 225 m. (a) At what angle should the highway engineer bank this curve so that vehicles traveling at 95 km/h can safely round it? (b) As car and truck ..
