How much force, assumed to be constant, doesBob apply to the rock in Newtons? What is Bob's maximum power output as hethrows the rock in kW? What is Bob's maximum power output as hethrows the rock in kW?Explanation / Answer
given the mass of the rock is m = 500 g = 0.5kg the speed of the rok is v = 30 m/s the distance moved is S = 1.0 m work done W = change in kinetic energy = 1/2 mv2 = ---------- J average force F = work /distance = W /S = -------------- N plug in the values ---------------- = ---------- J average force F = work /distance = W /S = -------------- N plug in the values ----------------Related Questions
