Three blocks are in contact and sitting on frictionless table. The first blog has a mass m1=1.2 KG, the second block has mass m2= 2.5 KG, and the third luck has mass m3 = 3.1 KG. An external force is applied causing three blocks to move together with the constant uniform acceleration od 1.9 m/s^2. What is the magnitude of the force exerted by the third block on the second block?

On Earth, you are able to consistently hit a golf ball 156 meters when you use your Five-iron which launches the ball at a 23 degree angle with respect to the ground. how far are you able to hit the ball
In lectures and in tutorials, we discussed the confinement of an electron (or other particle) to a box of infinite depth, running from x = 0 to x = a. If we, instead, define this 1-D region of confinement as running from -(a/2) to (a/2)
