force*time= changemomentum
force*time= 15*0 - 13.8*2.5
solve for force.
A squid with a mass of 15 kg ejects 1.8 kg of water downward through its funnel and moves from rest to a speed of 2.5 m/s (UP) from the sea bottom in 0.5s. Find the average force on the squid, neglecting drag forces and assuming constant acceleration.
