A block of mass .250 kg traveling at (1.0 m/s)y hits a second block with a .375 kg mass travelling at (1.2m/s)x.
a) What is the velocity of the 1st block after they hit each other? Assume the 2nd block has a velocity of (.10m/s)x + (0.37 m/s) y.
b) 2nd block encounters a rough patch on the table, where the coefficient of friction is .30. How far does the block go before it stops?
A bartender slides a beer mug at 1.30 m/s towards a customer at the end of a frictionless bar that is 2.0m tall. The customer makes a grab for the mug and misses, and the mug sails off the end of the bar.
The magnitude of the acceleration due to gravity
Many communications satellites orbit the earth in geostationary orbits. (They appear to remain in the same positions in the sky for observers on the earth's surface.) If such a satellite orbits at a height of 40,000 km, estimation the time delay in a..
A toy cork gun contains a spring whose spring constant is 10.02 N/m. The spring is compressed 5.0 cm and then used to propel a 6.00 g cork. The cork, however, sticks to the spring for 1 cm beyond its unstretched length before separation occurs. The m..
A proton is initially at rest at a point where the potential is 459 V. Sometime later the proton is at a point where the potential is 218 V. If no force other than an electrostatic force acts on the proton, what is its final kinetic energy.
An 9.00 {rm kg} point mass and a 15{rm kg} point mass are held in place 50{rm cm} apart. A particle of mass m is released from a point between the two masses 19{rm cm} from the 9{rm kg} mass along line connecting the two fixed masses.
A calorimeter contains 2000 grams of water at 0oc. a jet of stream at 100oc is passed through the water. What is the temperature of the water when 100 grams of steam have condensed in it.
A massless rod of length 1m has a 2.00 kg mass attached to one end and a 3 kg mass attached to the other. The system rotates about a fixed axis perpendicular to the rod that passes through the rod 30.0 cm from the end with the 3kg mass attached. The ..
As part of a safety investigation, two 1700kg cars travelling at 25 m/s are crashed into different barriers. Find the average forces exerted on (a) car that hits a line of water barrels and takes 1.3 seconds to stop, and (b) car that hits a concrete ..
What are vertical and horizontal components of the ball's momentum immediately after striking the crossbar. what is an average acceleration of the ball during this time interval.
A pencil (mass 5.8g and length 8.3cm) is at first balanced so that it is sitting vertically on a flat table. If the pencil then falls, find its angular velocity just before it strikes the tabletop. Assume that the mass of the pencil is distributed un..
A crate of 48.0 tools rests on a horizontal floor. You exert the gradually increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 344. After that you must reduce your push to 260 to keep it moving at ..
