(1/2) kx^2 , where k is the stiffness and x is the amount the spring is stretched, or compressed. Therefore, PE = (1/2)(200)(0.75) 2 = 56.25 J The kinetic energy of a particle is: (1/2) mv 2 , 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) v 2 If we assume energy is conserved, then PE = KE Solving for the velocity of the arrow v we get v = 47.4 m/s |
