Um ônibus está viajando numa estrada retilínea com a velocidade de 20 m/s. Vendo adiante um congestionamento no trânsito, o motorista aplica os freios durante 2,5 s e reduz a velocidade para 15 m/s. Supondo que a aceleração é constante durante o período de aplicação dos freios, calcule o seu valor, em m/s²?
