Thank you, I'll return with my calculations shortly. :) Just one question, how will I determine her initial velocity? I am not given her velocity, but only her distance.

Homework Statement Valentina, the Russian Cosmonaut, goes outside the ship for a spacewalk, but when she is floating 15m from the ship, her tether catches on a sharp piece of metal and is severed. Valentina tosses her 2.0kg camera away from the spaceship with a speed of 12m/s. a.) How fast...

Thank you very much :)

Homework Statement Anthony and Sissy are participating in the "Roll-a-Rama" roller-skating dance championship. While 75kg Anthony roller-skates backwards at 3m/s, 60kg Sissy jumps into his arms with a velocity of 5m/s in the same direction. m1= 75kg v1= 3m/s m2= 60kg v2= 5m/s v' = ?Homework...

Never mind, I was able to solve it. :D .012kg * 1/2(20m/s)^2 / .002m = 1200 N Too easy :)

Homework Statement During an autumn storm, a 0.012kg hail stone traveling at 20.0m/s made a 0.20cm deep dent in the hood of Darnell's new car. What average force did the car exert to stop the damaging hail stone? m= 0.012kg v= 20m/s d= .002m Homework Equations p=mv j= f delta t...
