How long does it take a 1000 Watt motor to pull 1334 N object upward height of 4 m?

Here's how to solve this problem, along with the assumptions we need to make:

aannames:

* No Friction: We're assuming there's no friction in the system (e.g., no air resistance or friction in the pulley system).

* constante snelheid: We're assuming the object is pulled upward at a constant velocity. This means the motor is only doing work against gravity, not accelerating the object.

Berekeningen:

1. Work Done: The work done to lift the object is:

* Work (W) =Force (F) * Distance (d)

* W =1334 N * 4 m =5336 Joules

2. Power: Power is the rate at which work is done:

* Power (P) =Work (W) / Time (t)

* We know the power (P) is 1000 Watts.

3. tijd: Solving for time:

* t =W / P

* t =5336 J / 1000 W =5.336 seconds

Daarom zou het ongeveer 5,34 seconden duren voordat een motor van 1000 watt een object van 1334 N omhoog trekt een hoogte van 4 meter, uitgaande van geen wrijving en constante snelheid.
