What is the kinetic energy of a 3 kilogram ball that is rolling at 2 meters per second?

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

How will the system respond to a temperature increase?

Find the mass by adding the numbers from the three sliders
