Abody a of mass 1.5kg, travelling along the positive x-axis with speed 4.5m/s, collides with another body b of mass 3.2kg which, initially, is at rest. because of the collision, a is deflected and moves with a speed 2.1m/s in a direction which is at angle 30° below the x-axis. b is set in motion at an angle θ above the x-axis. calculate the velocity of b after the collision

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
