A5.08 g object moving to the right at 28.5 cm/s makes an elastic head-on collision with a 10.16 g object that is initially at rest. 28.5 cm/s 5.08 g 10.16 g find the velocity of the first object immediately after the collision. the acceleration of gravity is 9.8 m/s 2 . answer in units of cm/s.

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
