94)
B)
V = rω
Therefore V0/rω = 1
for 94 angular abt a point on ground conserve kara le
93 mein can u gimme a conceptual explaination ki y is the ans c
solve karke to aa hi raha hai...
for 94 conserving angular momentum about point of contact
mvr=Iω
mvr=(mr2/2)ω
v/rω=1/2
for 95
F-f=ma
F.R/2+f.R=I.a/R
F/2+f=Ia/R2
F/2+F-ma=Ia/R2=2ma/5
3F/2=7ma/5
a=15F/14m
2a=15F/7m
