An old Chrysler with mass 1900 kg is moving along a straight
stretch of road at 48 km/h. It is followed by a Ford with mass 1200
kg moving at 40 km/h. How fast is the center of mass of the two
cars moving?
km/h
Homework Answers
using the equation we have
v(com) = m1v1 + m2v2 / m1 + m2
= 1900*48 + 1200*40 / (1900+1200)
= 44.9 km/h
so the velocity of COM is 44.9 km/h

A cycler is moving along a straight stretch of road after starting at/=0. The velocity of the cycle is given by the graph to the right. Assume that positive velocity represents when the cycle is moving away from its starting point and negative velocity represents when the cycle is moving toward its starting point. At what point in time was the cycle moving most rapidly? Explain your claim. At what point in time was the cycle at a maximum distance...
