1. A rider on a bicycle with a total mass of 80 kg rounds a curve with a radius of 20 meters at a speed of 10 km/hr.
a. What is the centripetal acceleration of the cyclist?
ac = 5km/hr ² or 1.39 m/s²
ac = √²/r
b. What is the amount of centripetal force acting on the bicycle?
Fnet, c = 111
What is the source of the centripetal force on the bicycle?
102/20
Fnet, c
= mac
80 × 1.39
6-kg ball is attached to a cord and spun in a horizontal circle with a radius of 1.2 m. The maximum tens
withstand is 60 N.
That is the maximum speed the ball can attain before the cord breaks?
= 10.95 m/s
Fc = mv²/r
60=0.6 v ²/1.2
