Question

KHW17- Ch8.2-4 Exercise 8.34 Part A Constants Find the magnitude of the velocity of these free-spirited otters right after they collide. Two fun-loving otters are sliding toward each other on a muddy and hence frictionless) horizontal surface. One of them, of mass 8.00 kg, is sliding to the left at 6.00 m/s, while the other, of mass 5.55 kg, is slipping to the right at 6.00 m/s. They hold fast to each other after they collide. m/s Submit Previous Answw uest Answer X Incorrect; Try Again; 3 attempts remaining; no points deducted Part B Find the direction of the velocity of these free-spirited otters right after they collide to the right to the left Submit Previous Answw Correct Part C How much mechanical energy dissipates during this play?

Explanation / Answer

m1V1+ m2V2 = (m1+m2) V

Here we take left as negative and right as positive

so, - 8 * 6 + 5.55 * 6 = ( 8 + 5.55 ) * V

so, V = - 0.9217m/sec

so, Energy dissipated = 0.5 m11 v1^2 + 0.5 m2 v2^2 - 0.5 (m1+m2)*V2

so, Energy dissipated = 231.532 J
