Question

European sports car dealer claims that his product will accelerate at a constant rate from rest to a speed of 100 km/h in 8 seconds. What is the speed after the first 5 seconds of acceleration?

Answer 1

`62.5[(km)/(h)]`

Step-by-step explanation:

if the required speed is 's', then it is possible to make up the next equation:

`(100)/(8) =(s)/(5);`

finally,

s=100*5/8=62.5 [km/h].
