Question 7 A Small Object Of Mass M Starts At Rest At The Position Shown And Slides Along The Frictionless Loop The Loop 1 (300.66 KiB) Viewed 46 times
Question 7 A small object of mass m starts at rest at the position shown and slides along the frictionless loop-the-loop track of radius R. What is the smallest value of y such that the object will slide without losing contact with the track? OA. R/4 OB. R O C. R/2 O D.2R OE. O
Moving to another question will save this response. Question 8 Let U be the potential energy (with the zero at zero displacement) and K be the kinetic energy of a simple harmonic oscillator. U avg and K avg are the average values over a cycle. Then: O A. Kavg = Uavg O B. Kavg> Uavg OC.K=0 when U = 0 O D.K+U=0 O E. Kavg < Uavg
