Si se aplica una fuerza de 30 N a un cochecito en reposo de 3 kg, ¿a qué velocidad final se llegará en 20 s?

Abaseball picther can throw a ball at about 90 miles per hour, v = 40 m/s, on solid rock ground. we now put him into space. when he throws the ball, which weighs mb = 0.15 kg moves away from himat the same speed. how long does it take the ball thrown in space to travel the 30 meters to the batter? he weighs mp = 100kg
