A 12 kg block (A) is sliding right with a speed of 2.2 m/s collides with a 20 kg block (B) which is traveling left at 3.0 m/s.
After the collision the 12 Kg block is moving left at a speed of 1.6 m/s
a) what is the velocity of the 20 kg block after the collision?
b) The collision lasts for 0.025s, what is the average force experienced by the 12kg block?
For a) i just used:
P = mv
Pa + Pb = Pa' + Pb'
plugged in the numbers and got Vb' = .72 m/s left.
I'm having trouble with part b) .. any ideas on how i could get started?
thanks
