Two objects of masses m and 4m are moving toward each other along the x-axis with the same initial speed v0 = 460 m/s. The object with mass m is traveling to the left, and the object with mass 4m is traveling to the right. They undergo an elastic glancing collision such that m is moving downward after the collision at a right angle from its initial direction. (a) Find the final speeds of the two objects. m = _________...

A uniform plank of mass 30kg and length 20m is supported by two
ropes T1 and T2 attached as shown on the diagram. Two masses 20kg
and 25kg are suspended are shown to keep the plank in equilibrium.
Find the tension T1 and T2 due to the two ropes.
I'm having trouble with this question. Would love to see the
actual work, so I can understand the concept.
