They ifted a total mass of mechanical work done by the two men in lifting the boat 24 times, assuming they applied the same by Sami Heinonen and Juha Matt The record number of boat lifts, including 653.2 kg approximately 4 in. off the ground a total of 24 times. Estimate the total force to the boat during each lift. (Neglect any work they may have done allowing the boat to drop back to the ground.) e @ a. K

Explanation / Answer

Given,

Total mass, m = 653.2 kg

The force required to overcome gravity in lifting the boat is 653.2 x 9.8 = 6401.36 N

The total of 24 lifts covered a distance of 24 x 4 in. = 96 in = 2.4384 meters

So the work done is 6401.36 N x 2.4384 m= 15609.07J
