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.

You are standing on a circular track that is 315 m long. You begin jogging at the start line and keep jogging until you complete one full lap and stop at the same point you started at. - What is the total distance you travel? - What is your final displacement? A world class sprinter ran 200 m in 21.75s. What was her average speed? (m/s)
6: In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. Assume a pilot’s speed upon impact was 54 m/s and the trees and snow stopped him over a distance of 7.6 m. Use a coordinate system where down is positive and, assuming constant acceleration, find the pilot’s acceleration after impact, in meters per second squared.
3. In Physics, the height of a free-falling object at a given time t is given by h = –16t² + v,t + h., where v, is the initial velocity, and h, is the initial height. A student throws a ball upward from a height of 48ft, initially at 32 ft/s. What is the maximum height of the ball?
A driver is driving uphill. He maintained his throttle, causing his car to constantly decelerate as it is coming up the hill. The road going up the hill is 217 m long and it took him 8.8 seconds to get to the top of the hill. His speed has reduced to 22 m/s at that point. What was the car's acceleration (include a negative sign in your answer)? Hint: the initial position of the car can be set at the origin.
