An archer puts a 0.30 kg arrow to the bowstring. an average force of 201 n is exerted to draw the string back 1.3 m.
a.assuming no frictional loss, with what speed does the arrow leave the bow?
b.if the arrow is shot straight up, how high does it rise?]

The computations for a and b are the following:

a. Work done = force x distance

= 201 x 1.3 = 261.3 J

KE = 261.3

261.3/(0.5 x 0.3) = v^2 = 1742, sq-root =

v = 41.74 m/s is the answer

b. 41.74^2 = 2gh

= 41.74^2/(2 x 9.8)

h = 88.89 m is the answer
