A 25 gram bullet traveling at 600 m/s, collides with a 3-kg block initially at rest. The bullet penetrates the block and exits with a speed of 75 m/s as shown below. After the collision, the block slides along a frictionless surface and engages a spring which brings the block to rest after being compressed a distance of 45 centimeters. Determine; a. The block's velocity immediately following the collision in m/s. b. The spring constant (k) in N/m. (Hint: the bullet may be disregarded in the second phase) c. The amount of kinetic energy lost by the bullet in Joules. d. Determine the magnitude of the impulse delivered to the bullet in kg-m/s. MC 3-kg 0 0 45 cm iw

A 25 gram bullet traveling at 600 m/s, collides with a 3-kg block initially at rest. The bullet
penetrates the block and exits with a speed of 75 m/s as shown below. After the collision, the
block slides along a frictionless surface and engages a spring which brings the block to rest after
being compressed a distance of 45 centimeters. Determine;
a. The block's velocity immediately following the collision in m/s.
b. The spring constant (k) in N/m. (Hint: the bullet may be disregarded in the second phase)
c. The amount of kinetic energy lost by the bulletin Joules.
d. Determine the magnitude of the impulse delivered to the bullet in kg-m/s.
