Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Learning Goal:
Two-segment travel. Practice the relationship
between speed - time - ditance in various ways
A car is making a trip in a total time of 110 min.
During the first 40 min its average speed is 30
mph

1 mile = 1609 m. ! hour = 60 minutes. I minute = 60 seconds.
Note: these basic conversion factors will be given to you in exams if needed.
Part A-What average speed of the rest of the trip is needed if the car's overall average speed of the entire trip is
51.82 mph ? Keep two digits after the decimal point.
Be careful: in general we CAN'T write Aveage speed of entire trip = (1/2) (1st segment speed + 2nd segment speed)
