- Squid rely on jet propulsion when a rapid escape is necessary. A 1.5 kg squid at rest pulls 0.10 kg of water into its mantle, then ejects this water at a remarkable 45 m/s. Right after this ejection, how fast is the squid moving?A 50.0 kg penguin is skiing, her velocity is facing north at 5.0 m/s. She runs into a 28.0 kg sea lion. After they are moving together at (velocity) of 2.0 m/s with an angle of 40 degrees north of east. Find the magnitude of the sea lions velocity before the accident?A 0.05 kg ball strikes a wall with a velocity v1 = -25 m/s and bounces back with a velocity v2 =5 m/s. If the collision lasts 0.2 s, then find the average force (in N) exerted on the ball.
- (a) A car traveling due east strikes a car traveling due north at an intersection, and the two move together as a unit. A property owner on the southeast corner of the intersection claims that his fence was torn down in the collision. Should he be awarded damages by the insurance company? Defend your answer. (b) Let the eastward-moving car have a mass of 1 300 kg and a speed of 30.0 km/h and the northward-moving car a mass of 1 100 kg and a speed of 20.0 km/h. Find the velocity after the collision. Are the results consistent with your answer to part (a)?A rock (rock 1) is flying in the sky towards another rock, rock 2. Rock 1 has a mass of 60 kg, and Rock 2 has a mass of 10 kg. Rock 1 is in the sky with a speed of 25 m/s towards Rock 2, and rock 2 is movingtowards Rock 1 in the opposite direction with a speed of 35 m/s. If the two rocks stick together, what is their final velocity? Ignore air resistance and gravity. Is there a change in the kinetic energy of the system? If so, what is it?A 5-kg sled has an initial velocity of 3 m/s when a 33-kg child, at rest, mounts it at the top of a hill (treat like a 1-Dimensional Perfectly Inelastic Collision).
