A honeybee with a mass of 0.150 g lands on one end of a floating 4.75-g popsicle stick, as shown in (Figure 1) . After sitting at rest for a moment, it runs toward the other end with a velocity v⃗ b relative to the still water. The stick moves in the opposite direction with a speed of 0.140 cm/s.

What is the velocity of the bee? (Let the direction of the bee's motion be the positive x direction.)

Express your answer to three significant figures and include appropriate units.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
