A child is pushing a 1.7 m wide door by applying a torque of 43 Nm counterclockwise. Find the tangential force applied by the child to the door. Express your answer as a whole number (no decimals) and add the appropriate unit.
Indicate your specific subject in the "School Subject" box, so those with expertise in the area will respond to the question.
The tangential force can be found using the formula:
Tangential force = Torque / Radius
Given, torque = 43 Nm and the radius = 1.7 m
Plugging in these values into the formula, we get:
Tangential force = 43 Nm / 1.7 m
Simplifying the expression, we find:
Tangential force = 25 N
Therefore, the tangential force applied by the child to the door is 25 Newtons (N).
To find the tangential force applied by the child to the door, we can use the formula:
Tangential force = Torque / Radius
where torque is given as 43 Nm and the radius of the door can be calculated as half of its width, which is 1.7 m / 2 = 0.85 m.
Now, let's plug in the values into the formula:
Tangential force = 43 Nm / 0.85 m
Calculating this, we get:
Tangential force = 50.59 N
Rounding the answer to a whole number, the tangential force applied by the child to the door is approximately 51 N.
