Answer to a math question 30. In 8 s, a car that starts from rest and moves with uniformly accelerated motion has achieved a speed of 72m/s. How much space must it travel to reach a speed of 90m/s?

Utilice v = u at para encontrar a que sea 9 m/s^2.
Utilice la misma fórmula para encontrar t con una velocidad de 90 m/s para obtener t como 10 s.
Utilice s=ut 1/2 at^2 para encontrar s como 450 m.
