A 14 g rifle bullet traveling 220 m/s buries itself in a 3.1 kg pendulum hanging on a 3.5 m long string, which

Answer 1

42

Answer 2

utilizing conservation of momentum for an inelastic collision, m0*v0=(m(pendulum)+m0)*v(new), hence the cost of the recent device might want to be m0*v0/(m(pendulum)+m0)=v(new). Now we use conservation of potential to make sure how the kinetic potential adjustments into gravitational potential potential. 0.5*m(device)*v(new)^2=m(device)*g*heigh... the position mass cancel and the height may be defined as height=v(new)^2/(2*g). height is the vertical displacement. Horizontal displacement may be found utilizing trigonometry. the bottom of the triangle, horizontal displacement, is what desires to be found. utilizing Pythagoras' theorem the hypotenuse is the length of the string, l, and one among the different aspects is =l-height. hence all you should do is horizontal displacement=sqrt(l^2-(l-height)^2)
