Question 3: Let us turn our attention to Impulse. a. (2 pts.) Using Newton's Third Law, explain the relationship between the force from the heavy c on the light cart and the force from the light cart on the heavy cart. Are they equal, or is one greater than the other? Show using words and equations. Include a free- body diagram of each cart with your explanation.

A helium balloon has mass, yet it doesn't fall to the floor. Is there a real force pushing up on the helium balloon? I know the answer is yes, but I don't understand why there is a force pushing it up.

1. When you drop a ball it accelerates downward at 9.8 m/s. If you instead throw it downward, then its acceleration immediately after leaving your hand, assuming no air resistance, is A. 9.8 m/s2 B. More than 9.8 m/s C. Less than 9.8 m/s D. Cannot say, unless the speed of the throw is given. 2. A heavy rock and a light rock in free fall (zero air resistance) have...

Since Moon is attracted to Earth, why doesn't it fall onto Earth? because it has large tangential velocity because there is another equal force on the Moon that balances gravity because centrifugal force balances gravity because centrifugal force more than balances gravity because it has too much inertia to fall towards Earth A. Ocean tides occur mainly because water always runs to the low spot water always runs to the side of the Earth away from the Moon B. water...

Q 4. (a) A body of mass m is moving in two dimensions in a constant z plane. Consider a coordinate system that rotates with constant angular speed 1 about the z-axis. In a fixed coordinate system (in the constant z plane), define the plane polar coordinates (r,0) while defining (r, ) as the corresponding plane polar coordinates in the rotating system. (i) In terms of the coordinate system rotating with constant angular speed 1, write down the kinetic energy...

(2) When we discuss body composition results with an individual, why do you think that we as health professionals should carefully choose our words and try to soften what otherwise may be a harsh reality of poor results? Keep in mind, that even though we will be particular with what we say, that doesn't mean we don't report results or just simply glaze over them to make the individual feel better. (3) Body composition is a very broad term as...
