A bullet with mass 5.04 g is fired horizontally into a 2.125-kg block attached to a horizontal spring. The spring has a constant 6.09 102 N/m and reaches a maximum compression of 5.79 cm.
(a) Find the initial speed of the bullet-block system.
(b) Find the speed of the bullet.
Estimate approximately the angular deflection of the muon's trajectory, given that the rest mass of muon is 100Mev and that the saturation magnetization in iron is equivalent to 1.6 x 10^23 electron moments per cm^3.
