The thin square plate has a semicircle cut-out. the center of the semicircle is coincident with the center of the square. if a = 41 cm, and r = 1.1 cm, how far to the left of the center is the centroid of the area? give your distance in centimeters with at least 4 significant figures.

divide the right side by the left side

0.024÷1.2=0.02 for example

conservation of mass

mass before something happens = mass afterwards

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
