3. ### A 4.5 g coin sliding to the right at 26.8 cm/s makes an elastic head-on collision with a 13.5 g coin that is initially at rest. After the?

(a) conserve momentum: 4.5g * 26.8m/s + 0 = 4.5g * -13.4cm/s + 13.5g * v v = 13.4 cm/s (b) KE = ½ * 0.0135kg * (0.134m/s)² = 1.2x10^-4 J Hope this helps!

5. ### 21.4 g marble sliding to the right at 56.8 cm/s overtakes and collides elastically with a 10.7 g marble moving?

Let's see if this works M1V1 + M2V2 = M1V3 + M2V4 taking right as the positive direction 21.4(56.8) + 10.7(14.2) = 21.4 V3 + 10.7(71) solve for V3 I get close to 28 m/s When you get a good response, please consider giving a...
