Homework Statement An unstable nucleus of mass 1.70 10^-26 kg, initially at rest at the origin of a coordinate system, disintegrates into three particles. One particle, having a mass of m1 = 5.40 10^-27 kg moves in the positive y-direction with speed v1 = 7.20 106 m/s. Another particle...

I looked at the answer key and the correct answer to that last part is 1.2m. I am still not sure how that was found but your reasoning makes sense I guess. Thanks for all the help!(:

So the two masses will pass each other at a height of two! Thanks! However, I am not sure I still understand why the 2.85 kg will keep moving; a bullet keeps moving but it is not attatched to a string like the mass in this problem is. Wouldn;t the length of the string limit how high the mass...

Thanks for explaining the thing about tension! I used the equation Mg-mg=(m+M)a and got 2.94 for the acceleration, sticking that into the velocity equation,v^2=Vo^2+2ax; Vo=0, a= 2.94, h=4 ;so v^2=2(2.94)(4) the speed it has when the 5.3kg mass hits the floor is 4.85. However, I am not sure how...

Homework Statement Two masses are connected by a light string passing over a light, frictionless pulley as in the figure below. The m1 = 5.30 kg object is released from rest at a point 4.00 m above the floor, where the m2 = 2.85 kg object rests. a) Determine the speed of each object when...

1. I need to set up a lab. The goal is to find the force of friction between a track and a ball. The track is flexible and tilted so that it slopes down. Looking at it from the side, the track looks like half of a U. The ball is released from the top of the track and somehow I have to figure out...
