Problem 22.17 (Multistep)
A coil of wire is connected to a power supply, and a current
runs in the coil. A single loop of wire is located near the coil,
with its axis on the same line as the axis of the coil. The radius
of the loop is 3 cm.
At time t1 the magnetic field at the center of the loop, due to the
coil, is 0.6 T, in the direction shown in the diagram; the current

A car with mass
mc = 1385 kg is traveling west through an
intersection at a magnitude of velocity of vc =
10.5 m/s when a truck of mass mt = 1984 kg
traveling south at vt = 12.6 m/s fails to yield

slide on the asphalt, which has a coefficient of friction of
μk = 0.5.

Introduction: In this lab you will investigate the conservation of linear momentum: momentum before an event equals momentum after an event if there is an absence of a non-conservative forces such as friction. The event is this case is a collision between two air track gliders. Two types of collisions will be studied. One is an elastic collision which will not be studied in this lab. after the collision. The second is an inelastic collision where after two objects collide,...
