If velocity of a particle depends on time 't' as v=t2−t−6 then find the time for which velocity remained negative
If velocity of a particle depends on time as v = t3+2√t. Then with what velocity is the particle moving at t = 4 sec and what is the displacement till then?
A particle starts moving rectilinearly at time t = 0 such that its velocity ‘v’ changes with time ‘t’ according to the equation v=t2−t where t is in seconds and v in m/s. Find the time interval for which the particle retards.
