A1.14 kg block is attached to a horizontal spring with spring constant 1700 n/m . the block is at rest on a frictionless surface. a 11 g bullet is fired into the block, in the face opposite the spring, and sticks. what is the bullet's speed if the subsequent oscillations have an amplitude of 10.0 cm? (express your answer in m/s as a pure number).

402 m/s

Explanation:

= Mass of bullet = 11 g

= Mass of block = 1.14 kg

v = Velocity of bullet

u = Velocity of block and bullet

x = Displacement of spring = 10 cm

k = Spring constant = 1700 N/m

The momentum of the system is conserved

Also,

So,

Velocity of bullet is 402 m/s

answer: its c lololo

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
