Object A has mass mA = 9 kg and initial momentum vector pA,i = < 17, -5, 0 > kg · m/s, just before it strikes object B, which has mass mB = 12 kg. Just before the collision object B has initial momentum vector pB,i = < 4, 5, 0 > kg · m/s. The forces that A and B exert on each other are very large but last for a very short time. If we choose a time interval from just before to just after the collision, what is the approximate value of the impulse applied to the two-object system due to forces exerted on the system by objects outside the system >> Fnet * delta_t =< >(vector form)
Find out the change in entropy of the system
A cylinder of gas at room temperature (20°C) has a pressure p1. To what temperature in degrees Celsius would the temperature have to be increased for pressure to be 2.7p1.
A bullet with mass m and speed v is fired at a ballistic pendulum bob of mass M. The bob is attached to a thin, light rod of length L, hangs vertically initially, and is attached to a pivot at its top end.
