Abowling ball encounters a 0.760-m vertical rise on
theway back to the ball rack, as the drawing illustrates.
ignorefrictional losses and assume that the mass of the ball
isdistributed uniformly. the translational speed of the ballis 3.50
m/s at the bottom of the rise. find the translationalspeed at the
top.

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
