s) An object has a velocity vo(t) = (300 m/s) ² + (1.00mlola
at time t= 0.004. The accelerations of the object is
a (t) = 42.00 m/s) ti + (1.00 m/sh) tag. If the object
is located at ro(t) = (1.00mle + (-1.00m) at time t = 0.002
?
What is the position of the object at time t= 1.00h?

Ответ:
La velocidad del más rápido deberá ser de 63 Km/h
Explanation:
Movimiento Rectilíneo Uniforme (MRU)
Un cuerpo se dice que tiene MRU cuando recorre iguales distancias en tiempos iguales y en línea recta.
Tenemos dos automóviles viajando en el mismo sentido. Uno, el más lento va por delante del otro que le ancanzará en t=6 horas una vez que supere la ventaja que le lleva el otro.
La velocidad se puede calcular con la fórmula:
Donde x es la distancia y t el tiempo que tarda en recorrerla.
El vehículo más rápido alcanzará al otro cuando logre superar los x=126 Km que le lleva. Si esto lo hace en t=6 horas, entonces la velocidad adicional que deberá desarrollar es:
Esa velocidad se suma a la del primer vehículo y tendremos la velocidad necesaria: 42 Km/h + 21 Km/h = 63 Km/h
La velocidad del más rápido deberá ser de 63 Km/h
