Intergated chemistry/physics
Draw a setup containing 3 gears. For every turn of the input gear, you need the output gear to spin 9 times. The drawing doesn't have to be perfect, but make sure to label the input gear, the output gear, and the number of teeth on each gear. Please E-mail me the picture a...

A 80 kg object slides at a 20 degree plane downward at 5m/s. An object 2 collides with object 1 by falling from 7 meter height and they stick together. Final speed of objects? I know the speeds would be the same. Would momentum equation work to solve this? The perfect inelasti...

Suppose a shipment of 500 machine parts contains 62 defective and 438 non-defective machine parts. From the shipment you take a random sample of 25. You are interested in the number of defective machine parts out of 25 trials and corresponding probabilities. When sampling with...

Calculus 2
how do I find the fluid force of a vertical semicircle that has been divided into three equal sectors of 60 degrees each. I know what the equation to find the fluid force for the whole semicircle is. but how do I find L(y) for each semicircle.

You are riding a 30 pound bicycle and you weigh 150 pounds. You are travelling at 20 miles per hour and fail to notice the 30 pound dog is in your path. If you transfer half of your momentum to this dog, what speed could he potentially reach?

Intergated chemistry/physics
Your teacher bumps into you in the hallway and knocks you down. After he apologizes, he asks you to figure out how fast he was going. By some magical coincidence, you just happened to be wearing a gauge that measured your mass to be 75 kilograms and your speed to be 25 miles p...

A 200 pound go-kart with a speed of 20 miles/hour collides with a 2nd go-kart (that was at rest) and causes it to move at a speed of 15 miles per hour. What is the mass of the 2nd cart if the first kart came to a stop upon collision?

Intergated chemistry/physics
A 10 pound bowling ball with a speed of 2.0 meters/second hits a 6 pound bowling ball. If the 10 pound bowling ball stops after the collision, what is the resulting speed of the 2nd ball in meters/second

Intergated chemistry/physics
A 200 man is running 3 miles per hour and collides with a 125 pound man. If the larger man transfers all of his momentum to the smaller man, will the smaller man travel slower, faster or at the same speed as the larger man?
