A baton is constructed out of two rigid rods that are at right angles. Determine the center of mass along the X direction and the Y direction.
The position of the masses are:
m1=3.0kg r1= -6.0i + 0.0j
m2= 4.0kg r2=0.0i+3.0j
m3=7.0kg r3= 6.0i+0.0j
m4=5.0kg r4=0.0i-3.0j
[the 'r', 'i' & 'j' have...
A car traveling on a straight road at 9.00 m/s goes over a hump in the road. The hump may be regarded as an arc of a circle of radius 11.0 m.
(a) What is the apparent weight of a 600-N woman in the car as she rides over the hump?
