.0000 Sprint * 100% 12:26 AM session.masteringphysics.com Problem 5.52 MasteringPhysics Problem 5.52 A fisherman has caught a very large, 5.0 kg fish from a dock that is 2.0 m above the water. He is using lightweight fishing line that will break under a tension of 59 N or more. He is eager to get the fish to the dock in the shortest possible time Part A If the fish is at rest at the water's surface, what's the least amount of time in which the fisherman can raise the fish to the dock without losing it Express your answer to two significant figures and include the appropriate units. min = Submit Give Up Incorrect Try Again; 4 attempts remaining Continue >Explanation / Answer
fish weight W = m*g = 5*9.8 = 49 N
max allowed accelerating force F = 59-W = 60-49 = 10 N
acceleration a = F/m = 10/5 = 2.0 m/sec^2
t = 2h/a = 4/2 = 1.414 sec
