A56.6 kg carpenter at a construction site plans to swing in a circular arc from one roof top to an adjacent roof at the end of a 12.8 meter rope suspended from a crane boom. if her wiry arms, toughened by years of driving spikes with a no. 22 framing hammer, are capable of exerting 1018 n of force on the rope, what is the maximum speed that she can tolerate at the low point of her swing? 15.2 m/s (t/f)

Answer

given,

mass of the carpenter = 56.6 Kg

length of the rope = 12.8 m

Force on the cable = 1018 N

maximum speed = ?

centripetal force =

                            =  

                            =  

gravitation force = m g = 56.6 x 9.8 = 554.68 N

 4.42 v² + 554.68  = 1018

  4.42 v² = 463.32

        v² = 104.82

        v = 10. 24 m/s

hence, maximum speed is equal to  v = 10. 24 m/s

 15.2 m/s speed is false.

the force required to move the cart is divided by three or 33.33 n.
