Question

Pls ans to be brainlist

Answer 1

Answer:

Explanation:3]for t=4 distance = put value od t=4 , in x=f[t]

2]Velocity at the instant =d[x]/d[t]=for 4 sec=t^2-5 t+6, and put value of t=4 we get=16-20+6=+2 m/sec

it is wrong question write question instantaneous velocity because we consider of an instant i,e 4 sec not of an time interval ,otherwise two time must be given .
