2) The 50-kg wheel is connected to a 10-kg
block as shown. The block is moving
downward with a speed of 2.4 m/S, and
suddenly, friction between the wheel and
ground was applied, and caused the block
to decelerate at 10.0 m/ S.
A) Draw the FBD and KD for the wheel alone,
and show all external and effective forces on
these diagrams.
B) Calculate the angular acceleration of the
wheel.
0.5 m
H=0.5
Ma = 10 kg
0.2 m
C) Assuming the wheel has angular
acceleration of 25 rad/ S find the acceleration
vector of the center of mass of the wheel.
