Question

Show major steps and formulas involved!!!!!, really need to understand how to get the results, if you can draw a picture, I will appretiate it!!!

89. A 5.00-g bullet mov- AMT ing with an initial M speed of v; = 400 m/s is fired into and passes through a 1.00-kg block as shown in Fig- ure P9.89. The block, initially at rest on a frictionless, horizontal surface, is connected Figure P9.89 to a spring with force constant 900 N/m. The block moves d = 5.00 cm to the right after impact before being brought to rest by the spring. Find (a) the speed at which the bullet emerges from the block and (b) the amount of initial kinetic energy of the bullet that is converted into internal energy in the bullet- block system during the collision.

Answer 1

After collision, Energy conservation for bock-spring system, Imut - & kan? (Lleg) (v2) = ( 900mm) ( 0 0sm) 2 = v= 1.5ml – speed et block just after collision, (a) monenturs conservation for collision, Pie = Pt mv, to = Met my (0.005) (400) = (11(1.5) + (0.005) u vp = 100118 6 Uhest = ki - Kq Thank = 3945
