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.

A car sits at rest at the starting line of a circular racetrack. It begins to accelerate at a constant rate (that 15, a constant angular acceleration) as it makes Its way halfway around the track. It then decelerates at the same constant rate during the second halt of the lap. It completes the entire lap in a time of 28.5 seconds. Also, the radius of the racetrack is 42.0 m. What is the car's top speed?A) 25.6 m/SB) 44.1 m/SC) 18.5 m/sD) 35.1 m/s
An ultracentrifuge accelerates uniformly from rest to 100,000 rpm in 2.0 min. If this ultracentrifuge accelerates 4.0 seconds starting from rest, what is the magnitude of the centripetal acceleration in unit of gravitational acceleration g for your sample sitting at 4.0 cm from the center axis? Use g = 9.8 m/s2. Hint: compute the centripetal acceleration in unit of m/s2 first, then divided by g will be your answer. For example, if your centripetal acceleration is 19.6 m/s2, your answer measured in unit of g is 2.0.
