(2-dimension) The fish from the previous problem swallows a smaller fish of mass 2 kg , while both fish are moving. If the smaller fish is moving upwards (90⁰ from the bigger fish) at a rate of 3 m/s, what is the speed and direction of the combined fish system after lunch?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
