In a lacrosse game a ball is thrown with a force of 2000 N. The throwing force acted for 0.8 seconds. If the ball had a change in velocity, Δv, of 50 m/s, what is the mass of the ball?

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
