Two masses are placed on an airtrack and given initial velocities towards each other. Mass one has a mass of 280 grams and is initially traveling at velocity 1.5 m/s in the x direction. Mass two has a mass of 510 grams and is initially traveling at velocity -2.5 m/s in the x direction. The two masses collide inelastically.
A/ Calculate the final velocity of the two masses.
B/ Calculate the impulse acting on mass one during the collision.
C/ Calculate the change in kinetic energy for the system during the collision.
A 1.5kg- block of ice is initially at a temperature of -7.0C a)If 2.6×10^5J of heat are added to the ice, what is the final temperature of the system? b)Find the amount of ice, if any, that remains.
