A car is rounding a curve as shown in the diagram. Which arrow correctly shows the direction of the centripetal force keeping the car in circular motion?
A
B
C

In the diagram of the car, if the driver took his hands off the steering wheel, which arrow correctly shows the direction the car would travel in?
A
B
C
D
Why do sharp turns in roads have reduced speed limits posted?
The lower the speed the lower centripetal force.
The lower the speed the higher centripetal force.
The lower the speed the larger the radius.
Speed limits aren't reduced on sharp turns.
If car A and car B are both traveling at the same speed, which will require a higher centripetal force?
Car A
Car B
They have the same centripetal force
If a sprinter runs in a circle of radius 50 m in 31 seconds at a constant speed, how fast were they running?
1.61 m/s
3.22 m/s
5.07 m/s
10.1 m/s
A bola is an old hunting instrument. If three rocks with a combined mass of 0.75 kg are spun at a speed of 20 m/s with a radius of 0.5 m, how much centripetal force is required to keep them spinning.
600 N
45 N
30 N
400 N
A car's tires can provide a frictional force up to 8500 N. If a 1000 kg car is traveling at 30 m/s around a bend with a radius of 25 m, will it safely make it around the curve.
No, the required centripetal force is too high.
Yes, the required centripetal force is higher than the frictional force.
An engineer is planning a road with a turn. If the speed limit is 20 m/s and the centripetal acceleration cannot exceed 8.5 m/s/s, how big must the radius of the turn be?
2.4 m
47 m
170 m
3400 m
What is the equation to calculate the centripetal force for an object?
F = mT
F = mv2/r
F = mu mg
F = mg

acceleration
A yo-yo is whirled on a string, then the string breaks. What causes the yo-yo to move off in a straight line?
centrifugal force
centripetal force
inertia
centripetal acceleration
A 12 kg object undergoes circular motion with a radius of 4 m and a speed of 18 m/s. What is the centripetal acceleration of the object?
1.125 m/s2
81 m/s2

36 m/s2
The diagram shows an object traveling at a constant speed in a circular path. Which labeled arrow represents the centripetal force acting on the object?
W
Z
X
Y
A 10kg car travels at a constant speed of 20.0 m/s around a horizontal circular track. Which diagram correctly represent the direction of the car's velocity (v) and the direction of the centripetal force (Fc) acting on the car at a particular moment?
