You are standing on a sheet of ice that covers the football stadium parking lot in buffalo; there is negligible friction between your feet and the ice. a friend throws you a 0.425 kg ball that is traveling horizontally at 12.0 m/s . your mass is 68.5 kg . for related problem-solving tips and strategies, you may want to view a video tutor solution of astronaut rescue. part a if you catch the ball, with what speed do you and the ball move afterwards? express your answer in centimeters per second.

0.074m/s

Explanation:

We need the formula for conservation of momentum in a collision, this equation is given by,

Where,

= mass of ball

= mass of the person

= Velocity of ball before collision

= Velocity of the person before collision

= velocity of ball afer collision

= velocity of the person after collision

We know that after the collision, as the person as the ball have both the same velocity, then,

Re-arrenge to find ,

Our values are,

= 0.425kg

= 12m/s

= 68.5kg

= 0m/s

Substituting,

The speed of the person would be 0.074m/s after the collision between him/her and the ball
