Lera25 [3.4K]

Answer:

2.815 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

$s=ut+\frac{1}{2}at^2\\\Rightarrow 1609.34=16.58\times t+\frac{1}{2}\times 0.0105\times t^2\\\Rightarrow \\\Rightarrow 4.905t^2+16.58t-1609.34=0$

$t=\frac{-16.58+\sqrt{308.69254}}{0.0105},\:t=\frac{-16.58-\sqrt{308.69254}}{0.0105}\\\Rightarrow t=94.25, -3252\ s$

Time taken with the acceleration is 94.25 seconds

Time = Distance / Speed

$\text{Time}=\frac{1609.34}{16.58}\\\Rightarrow \text{Time}=97.065\ s$

Difference in time = 97.065-94.25 = 2.815 seconds
