A group of physics students hypothesize that for an experiment they are performing, the speed of an object sliding down an inclined plane will be given by the expression v=2gd(sin(θ)−μkcos(θ))−−−−−−−−−−−−−−−−−−−√v=2gd(sin⁡(θ)−μkcos⁡(θ)). For their experiment, d=0.725meterd=0.725meter, θ=45.0∘θ=45.0∘, μk=0.120μk=0.120, and g=9.80meter/second2g=9.80meter/second2. Use your calculator to obtain the value that their hypothesis predicts for vv.
