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.

1.26 m/s

Explanation:

Given

translation speed of ball =3.5 m/s

Moment of inertia of ball about com

Initial Energy

Final Energy

Equating energy as no energy loss take place

m term get cancel

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
