The metal ball has a mass of 2.1g. It falls a distance of 0.80m between being released and reaching the bottom of the tube. (1) Calculate the gravitational potential energy transferred from the ball as it falls. gravitational potential energy transferred = [2] (ii) When the ball reaches the bottom of the tube, it has a speed of 1.2m/s. Calculate the kinetic energy of the ball at the bottom of the tube. kinetic energy = [3]

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 ?

Which basic property determines a colored light's placement on the spectrum of visible light? a. speed b. frequency c. amplitude d. velocity

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
