1.
A 2 kg mass is spun on a string in a horizontal circular path at a constant speed.
a. Draw the free-body diagram for the mass.
b. If the radius of the path is 0.5 m and the period of revolution is 0.25 s, what is the speed of the
mass?
What force is keeping the mass in a circular path?
I
d. What is the net force acting on the mass in the horizontal direction?
C.
2. A 1000 kg car travels around a circular track at a constant speed.
a. Draw the free-body diagram for the car (as viewed from the front of the car).
b. If the radius of the path is 200 m and the car is traveling at 25 m/s, how long does it take the car to
make a lap around the track?
C. What is the net force acting on the car in the horizontal direction?
d. What force is keeping the car in a circular path?
3. What force does the ground exert on a 1,000 kg car as it moves at 15 m/s through a dip in the road with
a path radius of 30 m?
