Given this, it's not surprising that cen which ended only in 1949, it's not surprising that centuries of whaling drove the species nearly to extinction. It's estimated that currently only about 400 individuals remain One of the reasons the population has been slow to recover is that n where they are susceptible to collisions with ships and entanglement in fishing gear The United States has taken protect right whales enter specific regions off the U.S coast that are important right-whale habitats. In addition, ships longer than 65 feet are required to slow down to 10 knots or less in certain critical areas, such as whale calving grounds. (Ship several steps to from shipping-related injuries. For instance, ships weighing more than 300 tons are required to report when they speeds are measured in knots, or nautical miles policies, researchers are working to understand what factors affect the sevenity of injury to whales a ship and a whale, the per hour, one nautical mile is 1.151 miles ) In order to guide whale Unfortunately, it's not always easy to gather information about the extent of whale injuries as a result of a in a collision One approach is to mat model the e of collisions. In one model of a collision duration of the impact decreases from 0 50 s for a ship moving at 5.0 knots to 0 38 s at 15 knots Because the collision is this short forces on the whale from water drag during the collision can be neglected PartA 4/4/2018

Explanation / Answer

As this force will be impulsive force, as impulsive force is rate of change of momentum. Impulse on both whale and ship will same magnitude, but will be in opposite directions. As mass increases, change in momentum will also increase. Hence impulsive force will also increase.

As mass is 10 times, speed is 5 knots time for impact will be same 0.5 seconds.

Henceimpulsive force will be A) It would be larger, but not as much as 10 times larger.
