Question

hlo please answer the qsn no. 16​

Answer 1

Answer:

C.

−2av3

if t = ax2+bx

then, differentiate both side with respect to time (t)

dtdt = 2axdxdt +bdxdt1 = 2axv +bvv.(2ax + b) = 1(2ax + b) = 1/v

Again differentiate both side with respect to time (t)

2adxdt = -v2.dvdt2av = - v-2.acceleration = -2av3

Hence, retardation= -2av3

I hope it helped you
