Centripetal acceleration Definition and 407 Threads

Hi I'm doing a lab report on centripetal acceleration and we are asked to find the centripetal acceleration using 2 formulas. (1)Acceleration Centripetal=Force Centripetal/Mass (2)Acceleration Centripetal=Velocity^2/Radius I get answers that are very close but I also have to answer the...

I have a lab that needs a graph, and my calculations seem logical, but I need some affirmation. In this lab we spun a string with a stopper attached at one end and some weights at the other end. We had to keep a part of the string at the same point while spinning and therefore it moved at a...

Can anyone please tell me how the formula for centripetal acceleration (a=v2/r) is derived?

A car travel in a loop when the car reach the top of the loop it's upside down. The radius of the loop stay the same but the velocity changes. I need to find the minimum velocity at the top of the loop without the car falling of the loop. Why does the centripetal acceleration of the car at the...

a) calculate the centipetal acc at the tip of a 4.00 m long helicopter blade that rotates at 300 rpm. 300 rpm = 31.42 rad/s = w Centrip Acc = rw^2 Ac = (3.41 rad/s)^2 * 4 m Ac = 3948.87 m/s^2 b)compare linear speed of the tip with the speed of sound which is 340 m/s v=rw v =...

******help With Centripetal Acceleration******* would someone PLEASE BE KIND ENOUGH TO PROVIDE ME WITH AN EXPLANATION OF CENTRIPETAL ACCELERATION? KINDA LIKE A SUMMARY OF THE TOPIC. EXAMPLES AND FORMULAS WOULD BE VERYYYYYYYYYYYYYYYYYYYYY APPRECIATED THANK YOU. PLEASE REPLY SOONNNN

The problem reads, A boy whirls a stone in a horizontal circle, 1.6m above the ground, by means of a string. The radius of the circular motion is 1.0m. The string breaks and the stone hits the ground 5.0m from the point directly below where the string broke. What was the magnitude of the...
