A vase falls off a table and shatters into three fragments which move away horizontally across the floor. Fragment 1 has half the mass of the original vase and travels with speed 34.5 cm/s. Fragment 2 has one-quarter the mass of the original vase and travels with speed 26.6 cm/s in a direction perpendicular to Fragment 1.
What is the speed (in cm/s) of the third fragment?
A vertical piston-cylinder device contains water and is being heated in top of a range. Through the process, 65 Btu of heat is transferred to the water and heat losses from the side walls amount to eight Btu.
An electron passes through a point 3.91 cm from a long straight wire as it moves at 33.7% of the speed of light perpendicularly toward the wire. The wire carries a current of 11.3 A. Find the magnitude of the electron\'s acceleration at that point.
A gas expands from I to F. The energy added to the gas by heat is 423 J when the gas goes from I to F along the diagonal path.
A cylinderical shaped metal rod is used to conduct heat. Whenthe temperature at one end is 100 degree Celsius and at the otherend is 20 degree Celsius, at what rate will heat be transferred between it ends

An object moves with constant acceleration 4.45 m/s2 and over a time interval reaches a final velocity of 12.4 m/s. If its initial velocity is 6.2 m/s, what is its displacement during the time interval
In a hydraulic system, the larger piston to be used to lift a 1670kg car has a diameter of 24.2cm, If instead compressed air at 115 psi of pressure is used, what is the largest mass car (in kg) that the system can lift
Two point charges are placed on the x-axis. The first charge,q1 = 8.00 nC, is placed a distance 16.0 m from the origin along the positive x-axis; the second charge, q2 = 6.00 nC, is placed a distance 9.00 m from the origin along the negative x-axis.
A skater body has rotational inertia 4.2 kg.m^2 with his fist held to his chest and 5.7 kg.m^2 by arm outstretched. The skater is twirling at 3.0 rev/s while holding a 2.5 kg-weight in all outstretched hand; the weights are .76 m from his rotational ..
