The work done would be 600 Joules (12 m x 50 N). Work is a measure of energy transfer when a force is applied to move an object over a distance in the direction of the force.
The minimum force required to lift a 50-N load using a single fixed pulley is 50 N. This is because a fixed pulley only changes the direction of the force applied, not the amount of force needed to lift the load.
The crate's acceleration would be 12 m/s^2, calculated as follows: Net force = (600 N) - (490 N) Net force = (50 kg) x (12 m/s^2)
The output force exerted by a movable pulley is equal to the input force applied. Therefore, if the input force is 50 N, the output force exerted by the movable pulley will also be 50 N.
Force = mass x acceleration F = ma In the problem we know the force exerted, the mass and the acceleration. F = 500 N m = 50 kg a = 9 m/s2 How much force was needed to get a 50 kg object to accelerate at 9 m/s2? Use the formula. F = ma =50 x 9 =450 N Force applied = 500 N Friction Force = 500 - 450 =50 N
To calculate the acceleration of the fall with air resistance, we need to consider the net force acting on the object. The net force is the difference between the force of gravity (weight) and the force of air resistance. Given that the weight of the object is 50 kg * 9.8 m/s^2 = 490 N, and the air resistance is 400 N, the net force is 490 N - 400 N = 90 N. Using Newton's second law (F = ma), the acceleration can be calculated as 90 N / 50 kg = 1.8 m/s^2.

50 N upward
The output force exerted by a moveable pulley when the input force is 50 N would be 50 N. Since a moveable pulley changes the direction of force but not its magnitude, the output force will be equal to the input force.
You can use Newton's second law, which states that force equals mass times acceleration (F = ma). In this case, the force exerted by the crane is 600 N, and the mass of the crate is 50 kg. So, you can rearrange the formula to solve for acceleration: a = F/m. Plugging in the values gives you acceleration = 600 N / 50 kg = 12 m/s^2.

The pressure would be 10 N/m². This is calculated by dividing the force (50 N) by the area (5 m²).
