Block 1 of mass 200 kg slides over a frictionless surface with a velocity of 0.25 cm/s and strikes block 2 of mass 100 kg sliding to the left at 0.75 cm/s. What is the final velocit

y of each block if the collision is

A) Perfectly elastic?

B) Perfectly inelastic?

C) If there is an external force of 4000 kg*cm/s^2 to the right for 0.008 s during the perfectly inelastic

Step 1

(A)

The final velocity of the each block strikes with each other if before the collision is perfectly elastic is,

Substitute the values,

Step 2

The final velocity of the each block strikes with each other if after the collision is perfectly elastic is,

Substitute the values,

Step 3

(B)

According to the conservation of momentum, the final velocity of each block strikes with ...
