Squids are the fastest marine invertebrates, using a powerful set of muscles to take in and then eject water in a form of jet propulsion that can propel them to speeds of over 11.5 m/s. What speed (in m/s) would a stationary 1.60 kg squid achieve by ejecting 0.105 kg of water (not included in the squid's mass) at 3.00 m/s? Neglect other forces, including the drag force on the squid.

Wwhat speed (in m/s) would a stationary 1.90 kg squid achieve by ejecting 0.115 kg of water (not included in the squid's mass) at 3.50 m/s? Neglect other forces, including the drag force on the squid. HINT m/sNASA's Saturn V rockets that launched astronauts to the moon were powered by the strongest rocket engine ever developed, providing 6.77 ✕ 106 N of thrust while burning fuel at a rate of 2.63 ✕ 103 kg/s. Calculate the engine's exhaust speed (in m/s). HINT m/sDan is gliding on his skateboard at 2.56 m/sm/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6.22 m/sm/s (as measured by an observer on the ground). Dan's mass is 42.1 kgkg and the skateboard's mass is 5.99 kgkg . If the jump requires 0.122 ss to complete, what average force did Dan exert on the skateboard?

- A 46,0-kg girl is standing on a 161-kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.461 m/s relative to the plank. (a) What is the velocity of the plank relative to the ice surface? 1 m/s (b) What is the gitt's velocity relative to the ice surface?Squids rely on jet propulsion to move around. A 1.50 kg (including the mass of the water inside the squid) squid drifting at 0.40 m/s suddenly ejects 0.10 kg of water to get itself moving at 2.50 m/s. If drag is ignored over the small interval of time needed to expel the water (why can we do this?), what is the water’s ejection speed relative to the squid? Include sketch
