Unformatted text preview: swallowing, the swordfish (and the mackerel inside it) move with a velocity of 5.30 m/s. Find the mass of the swordfish. Treat this is an inelastic collision. (15) (80.0 kg) 3. A 1.00 kg block is moving with an unknown velocity when it collides elastically with a stationary , 3.00 kg block. See below. After the collision, the 3.00 kg block slides a distance of 1.20 m before stopping. Find the velocity of the 1.00 kg block before and after the collision. For full credit, you must use energy principles. (15) (6.86 m/s, -3.43 m/s) k = 0.500 1.25 m 30.0 k = ? 3.75 m/s 4. A block starts from rest and slides down a ramp. It reaches the bottom of the ramp with a speed of 3.75 m/s. See below. Find k . For full credit, you must use energy principles. (15) (0.246)...
