**Question **# (a) Find the final velocity of the other gurney (b) The amount of kinetic energy lost in the collision. Two wayward hospital gurneys travelling towards each other collide. These have masses of 37 (7)kg and 45 kg. The heavier of the two is travelling at 4.3 m/s, and the other is travel at a speed of 3.7 m/s. After the collision, the heavier gurney is still travelling forward in the same direction, but at 0. 12 m/s. and amount of kinetic energy lost in the collision. (Hint make sure you do a sign convention, write down all known and unknows and convert to SI units, and write down any assumptions)
