Question

I did not have time to complete part D in lab so I could not complete the chart in the picture. Could someone help me to answer question 2 and 3 ? D. Matched Centripetal Force Trials. manually adjust your spin speed to achieve a target value of Fe) for the Baseline and Modified conditions I. First, calculate the expected values of isted in the table below, All trials are toresult in 20N 2. Spin the apparatus to produce Fc 2.ON using the baseline values ofrand m. Make sure agrees with calculations to within (+/-10%) 3. Now adjust r and mass to the indicated values and measure necessary values of T to achieve the same Fe as in the baseline test (2.0N) 4. Compare your expected and actual ratios of the periods in Centripetal conditions r (m) Woozo Masskg) FeN) TT(sec) TT(sec) T% (labeled) (measured) Reduced r (only) Reduced mass (only) .260 Reduced both m & r .130 *refer to equation 2b Questions: l. What force is providing the centripetal force in this experiment? The object that is spinning in curcubr mohon with the mass M is providing the centri petal force in this experiment 2. In part D, Fe was equal for all four trails. Each of the trials had a unique combination of radius and mass. Which pair of trials had the greatest centripetal acceleration? Which pair had the least? (a 4m r/T) Conceptually, using Newton's 2nd aw, explain why the four sets of conditions result in only two different levels of acceleration. 3. Calculate the number of"g's" the mass was subjected to under both the maximum and minimum ac conditions in the previous question. The "number" of g's is the factor by which the acceleration is greater than the acceleration due to gravity and is thus it is the actor by which the mass actually "feels like it weighs more than normal. To put this in perspective, at about 5g's of acceleration most human beings become unconscious, however fighter pilots can withstand about 10 g's for a while. A continuous acceleration of 15 g's is lethal to humans

Explanation / Answer

by Newton law of motion

centripetal force=Fc=mv^2/r =mass*centripetal accleration

so we can say that whose mass is less,accleration will be more and vice versa

so reduced mass will have greatest accleration as Fc=constant always

least accleration will be of Baseline and of one with reduced r

3) for maximum

accleration=a=Fc/mass=70.54

no of g=a/g=7.2

for minimum

a=F/mass=17.63

no of g=1.8
