Question

oblem 1.57 The Nando nng is a circular test track for cars, It has a of 12.5 km. Cars travel around the track at a constant speed of 100 km/h.A car starts at the eastemmost point of the ring and drives for 75 minutes at this speed. Part A What distance, in km, does the car travel? Express your answer to two significant figures. Mr Answers Give Up Incorrect: Try Again: 4 attempts remaining Part B What is the magnitude of the car's displacement, in km, form its intial positon? Express your answer to two significant figures. My Answer Part C What is speed of car in m/s? answer to two significant figures. Express your previous 19of

Explanation / Answer

a) speed = 100 kmph , time = 7.5 minutes

distance travelled = speed *time = 100*7.5 / 60 = 12.5 km

b) total displacement will be zero . because it is moving in a circular orbit and reached the initial position

c) 100 kmph = 100*1000/3600 = 27.78 m/s
