how far will 350 j raise a block weighing 7 N
To determine how far a 350 J force will raise a block weighing 7 N, we need to calculate the work done and then use it to find the displacement.
First, let's understand the formula for work (W) in this context:
Work (W) = Force (F) × Displacement (d) × Cosine of the angle between the force and the direction of displacement.
Since we are only given the force and the weight, we assume that the force is being applied vertically upward to counteract the weight.
In this case, the angle between the force and the displacement is 0 degrees, making the cosine of the angle 1.
So, the equation becomes: Work (W) = Force (F) × Displacement (d) × 1
Since the weight (force) is given as 7 N and the work done (W) is given as 350 J, we can substitute these values into the equation.
350 J = 7 N × d
To solve for the displacement (d), we rearrange the equation:
d = 350 J / 7 N
d = 50 m
Therefore, a force of 350 J will raise a block weighing 7 N by a distance of 50 meters.
