Squids rely on jet propulsion to move around. a 1.50 kg squid (including the mass of water inside the squid) drifting at 0.40 m/ssuddenly ejects 0.14 kg of water to quickly get itself moving at 2.50 m/s. if drag is ignored over the small interval of time needed to expel the water (the impulse approximation), what is the water's ejection speed relative to the squid?

-22.5 m/s

Explanation:

= Mass of squid = 1.5 kg

= Mass of water ejected = 0.14 kg

= Velocity of squid = 0.4 m/s

= Velocity of squid after ejection = 2.5 m/s

v = Velocity of water ejection

In this system the momentum is conserved

The velocity of the water ejection relative to the squid is

-20+(-2.5) = -22.5 m/s

The negative sign indicates the opposite direction to the direction of the squid.

the force required to move the cart is divided by three or 33.33 n.

real, smaller and upside-down.   so the answer should be b.
