The starship Enterprise and the Millennium Falcon are both stationary, docked in space so that the crews can exchange cookies. They later depart at the same time with Han Solo directing the Millennium Flacon at a speed of 300 m/s at an angle 45 degrees to the initial direction of Captain Kirk in the Enterprise which moves off at 400 m/s. At the instant the two vessels separate Captain Kirk realizes he left his favorite tea-cozy on the Millennium Falcon and directs Lieutenant Sulu to alter course to intercept Han Solo. What acceleration must the Enterprise undergo for its path to intersect the path of the Millennium Falcon in 40 seconds?

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

A23 kg log of wood begins from rest, 300 m up a sluice (a water track used to transport logs, think of it as an inclined plane with negligible friction) inclined at 20° to the horizontal. after it reaches the flat waterway at the bottom it collides elastically with a 100 kg block of wood initially at rest near the base of the incline. (a) how long does it take the 23 kg log to travel down the incline? (b) what is the speed of the 23 kg log at the bottom of the incline? (c) what are the velocities of both blocks of wood after the collision? (d) what is the total kinetic energy before the collision? (e) what is the kinetic energy of the 23 kg log after the collision? (f) what is the kinetic energy of the 100 kg block of wood after the collision? (g) what is the total kinetic energy after the collision? (h) compare the total initial and total final kinetic energies. is this consistent with what you would expect for elastic collisions? explain!
