si un disco fue lanzado con una fuerza de 1000 N, y el disc recorrió una distancia e o.6 m ¿Qué trabajo efectuó el lanzador ?

Alexeev081 [22]

Answer:

Trabajo realizado = 600 Nm

Explanation:

Dados los siguientes datos;

Fuerza = 1000 Newton

Distancia = 0.6 metros

Para encontrar el trabajo realizado;

$Trabajo \; realizado = fuerza * distancia$

Sustituyendo en la ecuación, tenemos;

$Trabajo \; realizado = 1000 * 0.6$

1. If Randy races his F-150 down Highway 1 for 2560 meters in 60 seconds, what is his average speed?

Nimfa-mama [501]

The average speed is 42.7 m/s

Explanation:

The speed of an object in uniform motion (=moving at constant speed) is given by the equation:

$v=\frac{d}{t}$

where

v is the speed

d is the distance

t is the time

For the car in this problem, we have:

d = 2560 m (distance)

t = 60 s (time)

Solving the equation, we find the average speed:

$v=\frac{2560}{60}=42.7 m/s$
