im gettin all except 64!!!!!!!!!im gettin its incresin!!!!!!!!max velocity is wa.....so as A increses vel. has to increase!!!!!

yep... i didnt notice the figure properly!!!!!![2]...

try 1st passage.. again

w=2pi/T and in fig T is doubled after each loop..

iitimcomin ·

ohh!!! its given in thee figure!!!! i didnt see!!!!

3
iitimcomin ·

but w is independent of amp.

33
Abhishek Priyam ·

64. v=Aω
v=A(2pi/t)

as A is doubled... T is also doubled... so v is constant..

66 is quite evident that we cant say..... no matter how long the amplitude increases the time period remains the same!!!!!!!!!!!

so its just like a normal SHM where u cannot predict where the object is a t any infinite time!!!!!!!!!!!!!!!!

Abhishek Priyam ·

ok i will solve that....

jsut wait.. and tension mat lo... tumhara sahi hoga..

i cant get 66.....can someone xplain....[2]

iitimcomin ·

does IN each half sine curve not include the 0 disp areas??????

iitimcomin ·

s orry in eqxn no. 6 we shud hav. Rα3 not Rα2............

7. b
8. c
9. c

i ahve not solved these.. these are the answers in book.. :p

64. c
65. b
66. d
67. d

after each 1/2 of time period the amp increases to double

y = AsinWt.....!!!!!

clearly the velcity increases!!!!!!!!!!

a = w^2A............ so it too goes on increasin!!!!!

min speed is evidently zero at max disp.!!!!!!!!!

66 i think it cant be determined!!!

eureka123 ·

yup priyam is correct...........try to form minimum eqns.....

33
Abhishek Priyam ·

take benefit of symmetry in question...

33
Abhishek Priyam ·

exam me kya karoge... 8 eqns ka... :P

3
iitimcomin ·

how does it matter yaar its all da same!!!

33
Abhishek Priyam ·

8-8 laoge to hoga hi...

u should have made less variables...

3
iitimcomin ·

too lazy to solve those eqxns!!!!!!!

33
Abhishek Priyam ·

u should match ur answers...

33
Abhishek Priyam ·

:P

ye mera doubt nahi hai its for others to solve..(so why u are giving equations.... ) so if u wish u solve and i will give the answer..

and in between 8 variables... :O

just 3,4 will do...
