<span>If the swimmer is swimming perpendicular to the current, it will take her 66m / 0.42 m/s = 157.14 seconds to cross the river. At the same time, the current will be taking her downstream at a rate of 0.32 m/s. So, when she reaches the opposite bank, her total downstream distance traveled will have been 0.32*157.14 = 50.28 meters.</span>
The force applied to raise a table to a height of 8m when 120 Joules of work is done is 15 N. That is, Force F = 15N
<h3>
What is Work ?</h3>
Work is the product of force and distance in the direction of force. Work is done on an object when the displacement of the object is in the direction of the force applied. That is,
W = F x S
The S.I unit of work is Joule.
Given that a table to a height of 8m and 120J of work was done. To find the force applies, the parameters to consider are
Make force F the subject of formula from the formula written above. That is,
F = W/S
F = 120 / 8
F = 15 N
Therefore, if the 120 Joule of work is done, the force applied to raise a table to a height of 8m is 15 Newtons.
