A4,000 kg boat floats with one-third of its volume submerged. if two more people get into the boat, each of whom weighs 690 n, what additional volume of water is displaced?

The weightiness of the added water displaced is equivalent to the joined weight of the two extra people who come to be into the boat:

m water g                   = 2 x 690 N

                                   = 1,380 N

The mass of the water displace is then

m water g                   = 1,380 N

                                   = 1,380 N / 9.8 m/s^2

                                   = 141 kg

Compute the calculation for density for the volume of water displace and practice this outcome for the mass of the water displace to get the

p water                      = mass of water / volume of water

volume of water        = mass of water / p water

                                  = 141 kg / 1000 kg /m^3 eliminate kilogram

                                  = 0.14 m^3 the additional volume of water that is displaced

explanation:

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
