An inventive child named Nick wants to reach an apple in a tree without climbing the tree, Sitting in a chair connected to a rope that passes over a trictioniess pulley (see figure beiois), Aick pulls on the loose end of the repe wth such a force that the spring scale reads $$340\mathrm{N}$$. Nick's true weight is $$290\mathrm{N}$$, and the chair neighs $$160\mathrm{N}$$. Nick's feet are not touching the ground. Use gu-9.8 m/s? 2 (b) Find No's acceleratiot, using upenend as positive. - $${\mathrm{Ns}}^2$$ (c) Find the miegritude of the force Nick exerts on the cheir. $$?N$$ (d*) Instead Aock hands the rope wath the scaie to his friend Bamey, who stands on the ground. Bamey puls on the rope so that the sprimg scale again reads 340 . What is Nicks acceiecation now, again using upward as positive. $$x\mathrm{mv}{\mathrm{s}}^2$$
