The acceleration of the dragster is 8.89 m/s².

To find the acceleration, the given values are,

V₀ = 85 m/s

V = 45 m/s

<h3>What is acceleration?</h3>

Acceleration is a rate of change of velocity with respect to time with respect to direction and speed.

$\overline{a} = \frac{v - v_0}{t} = \frac{\Delta v}{\Delta t}$ `

a = acceleration

v = final velocity

v₀= starting velocity

t = time

Substituting the given values in the formula,

a = (V-Vo)/time

= (45-85m/s)/4.5 s.

a = 8.89m/s².

Thus, the acceleration a of the dragster is 8.89 m/s².
