A 45.0 kg uniform rod 4.40 m long is attached to a wall with a hinge at one end. The rod is held in a horizontal position by a wire attached to its other end. The wire makes an angle of 30.0 ∘ with the horizontal, and is bolted to the wall directly above the hinge. If the wire can withstand a maximum tension of 1300 N before breaking, how far from the wall can a 70.0 kg person sit...
Part A Select the equation that shows that the gravitational potential energy of a 1300-kg boulder raised 4 m above ground level is 52000 J. (You can express g in units of N/kg, because m/s? is equivalent to N/kg) mgh = (1300 kg)(10N/kg) (4 m)-52000 J 2 2 421) N2000J 0 PE-yMgh-V(1300kg)(10N/kg)(4m) o PE-mg-(1300 kg)(10 N/kg) (4 m) 52000 J PE = mgh = (1300 kg)(10 N/kg)(4 m) = 52000 J Submit Provide Feedback Next >

Question 5 O out of 20 points C A 79 kg toy plane is attached to a 7.2 m long string and traveling in a horizontal circle with uniform circular motion. If the maximum tension x the string can provide before breaking is 84 N, what is the highest tangential speed the plane can move at without breaking the string? Selected Answer: [None Given) Response in this example, the tension of the string is providing the centripetal force that keeps...
A 20.0 kg wood ball hangs from a 2.10 m-long wire. The maximum tension the wire can withstand without breaking is 400 N. A 0.900 kg projectile traveling horizontally hits and embeds itself in the wood ball. What is the largest speed this projectile can have without causing the cable to break?
