A bullet with a mass of 0.05 kg is fired in a straight line at a 2 kg wheel with
a radius of 0.3 m that is fixed to rotate about its center. Model the wheel
as a solid cylinder with I = % M R2. The bullet hits the wheel at a vertical
distance of y = 0.2 m above the center of the wheel and explodes through
to the other side. After the collision, the wheel is rotating with an angular
speed of 3 rad/s, while the bullet is moving at a translational speed of 50
m/s. Assume the system is isolated with negligible loss of mass in the
collision. Find the speed of the bullet before it collided with the wheel.
w = 3 rad /s
Ve=50 m/s
y= 0.2 m
m=0.05 kg
R=0.3 m
M= 2 kg

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
