Aboat with a horizontal tow rope pulls a water skier. she skis off to the side, so the rope makes an angle of 12.0 ∘ with the forward direction of motion. for related problem-solving tips and strategies, you may want to view a video tutor solution of pushing a stalled car. part a if the tension in the rope is 200 n, how much work does the rope do on the skier during a forward displacement of 320 m?
We have a force with a horizontal component given by the angle of 15°. So wue can take this component to calculate the total work done, that is,
Our values are,
Substituting in Work equation,
your answer would be fusion
answer: the rock sample is a sedimentary rock.
it is given that:
mass of rock sample, m = 2.7 g
volume of rock sample,
so, density of rock sample will be
since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
