Answer:
Explanation:
If the dragster  attains the speed equal to that of the car which is moving with constant velocity of v₀ , before the two close in contact with each othe , there will not be collision .
So the dragster starting from rest , must attain the velocity vâ‚€ in the maximum time given that is tmax .
v = u + a t
vâ‚€ = 0 + a tmax
tmax = vâ‚€ / a
The value of tmax is vâ‚€ / a .
