Assume that the force of a bow on an arrow behaves like the spring force. in aiming the arrow, an archer pulls the drawstring back 56 cm from its rest position and holds it in position with a force of 158 n. if the mass of the arrow is 58 g and the "spring" is massless, what is the speed (in m/s) of the arrow immediately after it leaves the bow?

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
