Answer:
El avión recorrió 45 km en los 180 s.
Explanation:
La relación entre velocidad, distancia y tiempo se da de la siguiente manera;
Por lo cual los parámetros dados son los siguientes;
Velocidad = 900 km/h = 250 m / s
Tiempo = 180 s
Estamos obligados a calcular la distancia recorrida
De la ecuación para la velocidad dada arriba, tenemos;
Distancia recorrida = Velocidad pf viaje × Tiempo de viaje
Distancia recorrida = 900 km/h × 180 s = 900
Distancia recorrida = 900 km/h × 1 h/60 min × 1 min/60 s × 180 s = 45 km
Por lo tanto, el avión viajó 45 km en 180 s.
Once the stone leaves the passenger's hand, its horizontal acceleration
stops. Its horizontal speed after that is whatever horizontal speed it had
at the instant it was dropped.
Its vertical acceleration ... its total acceleration with respect to the rails,
is 9.8 m/s² straight downward ... the acceleration of gravity.
Centripetal acceleration

Direction of force also towards centre
Answer:
48 m
Explanation:
An object is said to be moving in uniform motion if its velocity is constant.
For an object in uniform motion, its average speed is given by the equation:
where
v is the average speed
d is the distance covered
t is the time taken
For the object in this problem, we have:
v = 6.0 m/s is the average speed
t = 8.0 s is the time taken
Solving for d, we find the distance traveled:
