A gas molecule having a speed of 300m/s horizontally collides elastically with another molecule of the same mass is initially at rest. After collision the first molecule moves at an angle of 30° to it's initial direction. Find the speed of each molecule after collision and the direction of the second molecule.

A student moves a box of books down the hall
by pulling on a rope attached to the box. The
student pulls with a force of 183 N at an angle
of 27.6
◦
above the horizontal. The box has a
mass of 41.2 kg, and µk between the box and
the floor is 0.28.Now the student moves the box up a ramp
(with the same coefficient of friction) inclined
at 10.6
◦ with the horizontal.
b) If the box starts from rest at the bottom
of the ramp and is pulled at an angle of 27.6
◦
with respect to the incline and with the same
183 N force, what is the acceleration up the
ramp?
