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.

Colonel John P. Stapp, USAF, participated in studying whether a jet pilot could survive emergency ejection. On March 19, 1954, he rode a rocket-propelled sled that moved down a track at a speed of 632 mi/h. He and the sled were safely brought to rest in 1.40 s (Fig. P2.41). Determine (a) the negative acceleration he experienced and (b) the distance he traveled during this negative acceleration.

A car is traveling at 96 km/h when the driver sees an accident 75 m ahead and slams on the brakes. What minimum constant deceleration (in m/s2) is required to stop the car in time to avoid a multi-car pileup? (Round your answer to two decimal places.)
A taxi traveling along a straight section of road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 33.0 m/s.

The Bugatti Veyron can go from 0-100km/h in 2.46s. It takes another 7.34s at a different acceleration to go from 100km/h to 240km/h. Assume the accelerations are constant. (Please include a diagram and convert km/h to m/s). a) Calculate the acceleration of the car over the first 2.46s. b) How much distance does the car have to cover to reach a speed of 240km/h? c) The speed of the car is limited to 415km/h to protect the tires. If the car maintains the acceleration that it had at 240km/h, how long would it take the car to reach 415km/h?
A man drives a car at v1= 54mi/h and suddenly notices a truck at a distance d= 13.5 m in front of him. That truck is moving in the same direction at a constant velocity v2= 34 mi/h. In order to not collide the person in the car must reduce their speed to v2 in a time interval, by slamming the brakes. the driver can give the car a maximum acceleration of ax. assume the acceleration is constant and the motion is in the positive direction. so that ax<0. 1) if the driver just barely avoids collision what is the final distance between the car and the truck? 2) write an expression for the distance Δx2 traveled by the truck in the time Δt, in terms of the quantities defined in the problem. 3) write an expression for the distance Δx1 traveled by the car in the time Δt, assuming the driver brakes as hard as they can. 4)Relate the total distance the car travels Δx1 to the distance the truck travels and the initial distance between them. 5)Find the acceleration of the car in terms of its…
