A rescue pilot drops a survival kit while her plane is flying at an altitude of 2000.0m with a foward velocity of 100.0m/s. If air friction is disregarded, how far in advance of the starving explorer's drop zone should she release the package.​

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
