A uniform speed is 0.45.
<u>Solution:</u>
F = mv^2/r
r = 0.2m
v = 0.75 m/s
m = 0.160 kg
F = 0.16*(0.75)^2/0.2 = 0.45.
If you spin a ball with a string or spin a lasso pulling on the rope will pull the object toward the center. Centripetal force is provided by the frictional force between the ground and the wheels as the car turns. A force acting on a moving object at an angle to the direction of motion that tends to cause the object to follow a circular or curved path.
The gravitational force acting on an orbiting satellite is an example of a centripetal force. The friction of a car's tires while cornering similarly exerts a centripetal force on the car. Satellites orbit around the earth due to the gravitational pull of the earth. Movement of electrons around the nucleus. Movement of the blades of the windmill.
