a. What is the centripetal acceleration of the cyclist?
1.39 m/s 2
ac = 5km/hr 2
ac = √²/r
102/20
& What is the amount of centripetal force acting on the bicycle?
Fret, c = 111
c. What is the source of the centripetal force on the bicycle?
Fnet, c = mac
80 × 1.39
2. A 0.6-kg ball is attached to a cord and spun in a horizontal circle with a radius of 1.2 m. The maximum tension the cord
can withstand is 60 N.
a. What is the maximum speed the ball can attain before the cord breaks?
b. If you wanted to maintain the speed of the ball from part a, would it be better to increase or decrease the radius to
ensure the cord would not break?
3. The Earth's orbit around the Sun is nearly circular with an average radius of 1.5 x 10¹1 m. Assume the Earth is in uniform
circular motion as it travels around the Sun.
