18. Uma bola está em repouso na marca do pênalti quando um jogador, ao chutá-la, aplica uma força F, fazendo-a sair com uma velocidade de 108 km/h . Sabendo que a bola tem massa de 600 g e que a duração do contato do pé do joga e dor com a bola foi de 2.0 * 10 ^ - 3 , calcule, em unidades SI: bola v = 108 km/h a) o módulo da aceleração média adquirida pela bola; b) a intensidade da força média trocada entre o pé do jogador e a bola.
