An archer pulls back 0.75 m on a bow which has a stiffness of 200 N/m. The arrow weighs 50 g. What is the velocity of the arrow immediately after release?

Re: Answer This And 2 Others For 10k, Students Only by Brokeguyy(m): 7:19pm On Aug 03, 2017
PE = (1/2)(200)(0.75)2 = 56.25 J

The kinetic energy of a particle is:

(1/2)mv2, where m is the mass and v is the velocity.

The arrow can be treated as a particle since it is not rotating upon release.

Therefore, the kinetic energy KE of the arrow is:

KE = (1/2)(0.05)v2

If we assume energy is conserved, then

PE = KE

Solving for the velocity of the arrow v we get

v = 47.4 m/s
