Question
  1. A 2 kg blob of puty moving at 3 m/s slams into a 2 kg blob of putty at rest. what is the speed of the two stuck together blob of putty immediately after collision?

      A.

    0.66 m/s

      B.

    1.5 m/s

      C.

    1m/s

      D.

    0 m/s

Expert Solution
Step 1

Given data:

Mass of the first blob of puty is,

m1 = 2 kg

Mass of the second blob of puty is,

m2 = 2 kg

The initial velocity of the first blob of puty is,

u1 = 3 m/s

The initial velocity of the second blob of puty is,

u2 = 0 m/s

Formula used:

For elastic/inelastic collision, linear momentum is conserved.

According to the conservation of linear momentum,

Initial momentum before collision = Final momentum after the collision
