A car in an amusement park ride rolls
without friction around the track shown
in the figure. It starts from rest at point
A at a height h above the bottom of the
loop. Treat the car as a particle.

03-Kinematics Part II
You are on the 12th story of a downtown building, 46.0 m above the ground. Your physics
professor, who is 1.80 m tall, is walking alongside the building at a constant speed of 1.20 m/s.

A 3.0-kg object has the following two forces acting on it:
1 = (16 + 12)N and
2 = (10 + 22)N.
If the object has an initially velocity
0 = (2 4) m/s , determine its velocity at t = 3.0s.

02-Kinematics Part I
The x-vs-t graph for the motion of a certain object is shown here.
a) Sketch the corresponding v-vs-t graph on the axes below.
b) Sketch the corresponding a-vs-t graph on the axes below.
Three forces act on an object to give it an acceleration of magnitude 2.5 m/s2. These three
forces are given as:
1 = (2.0 + 2.0 1.0),
2 = (5.0 + 3.0), and
3 = (6.0 2.0).
a) What is the mass of the object?
b) If the ob
