A motorcycle with a mass of 100 kg travels around a flat, circular track with a radius of 10m with a constant speed of 20m/s. a. What type of centripetal force is keeping the motorcycle moving on the path?

b. What is the magnitude of the force required to keep the motorcycle moving in a circular path at this speed?

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

answer: 31, 5556. 952 seconds

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
