The velocity of a particle moving with constant acceleration at an instant `t_(0)` is `10m//s` After 5 seconds of that instant the velocity of the particle is 20m/s. The velocity at 3 second before `t_(0)` is:-
Text Solution
Verified by Experts
The correct Answer is:
C
`R=Cv_(0)^(n)` Putting data from table: `8=Cxx10^(n)` `rArr 31.8=Cxx20^(n)rArr 31.8/8=3.9 cong 4=2^(n) rArr n=2`
