You are hired to design a stage set where a m=65 kg actor canswing from a cable of length R without falling held by the onlysandbag the company owns which weighs ms=130 kg. What is themaximum angle the actor can swing without falling?
A compress spring launches a m=20g metal ball at θ=30° afterbeing compressed d=20 cm. The ball travels with negligible airresistance and lands x=5 m away from the launch point, which wash=2 m above the landing zone. Determine the spring constant, k.
A student, m=75 kg, is pushed by two springs, k1=1.5 N/m, k2=2.5kN/m through a frictionless slope, h=10 m, until the θ=30° inclinewhich has µk=0.15. How far, x, along the incline will the studentgo?
