1. A 0.2 kg hockey puck undergoes a slap shot moving 14 m/s to the left side of the goal. The goalie moves to stop the puck at 3 m/s to the left also. The goalie saves and blocks the shot and the puck collides into a
1.5 kg glove of the goalie and the glove with the puck both continue moving to the left. Calculate the
velocity of the glove and puck moving immediately after the collision.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
