Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (3.0, 0.0) m, 3.0 kg at (0.0, {y1}) m, 4.0 kg at (0.0, 0.0) m and a fourth object of 8.0 kg at (2.0, {y2}) m. Find y coordinate of center of gravity for this configuration. Enter your unit as “m”.

A girl of 50.0-kg skating at 10 m/s crashes into another girl of mass 35.0-kg moving in the same direction at 8.0 m/s. Assuming the impact lasts 0.15 s, after which they move together, how much energy is lost in this collision (the absolute value in J)? Enter your unit as “J”.

A 50.0-g uniform meter stick is supported by a fulcrum at the 30.0-cm mark. A 100-g mass is hung at the 50.0-cm mark. What mass (in g) should you place at the 10.0-cm mark to perfectly balance the stick in horizontal position? Enter your unit as “g”.

A girl of 50.0-kg skating at 10 m/s crashes into another girl of mass 35.0-kg moving in the same direction at 8.0 m/s. Assuming the impact lasts 0.15 s, after which they move together, what is the average force that the 50.0-kg girl exerts on the 35.0-kg girl during the crash? Enter your unit as “N”.
