A car is parked on a cli® overlooking the ocean
on an incline that makes an angle of 22:0±
below the horizontal. The negligent driver
leaves the car in neutral, and the emergency
brakes are defective. The car rolls from rest
down the incline with a constant acceleration
of 4.60 m/s^2 and travels 48.0 m to the edge of
the cliff. The cliff is 38.0 m above the ocean.
The acceleration of gravity is 9.81 m/s^2.
a) How long is the car in the air? Answer
in units of s.

What is the car's position relative to the
base of the cliff when the car lands in the
ocean? Answer in units of m

y=x^4+bx^2+8x+1 has a horizontal tangent & a point of inflection for the same value of x. What is the value of b?

I took the first derivative. Then I took the second derivative. I don't know where to go from there to find b. Any tips? Thank you in advance.

How do you determine whether lines are parallel, perpendicular or neither? The equations given are y=1/3x +1/2 and y=1/3x-2. Once again please show me how you came to your answer. I do not just want the answer I need to see how you came to your answer, maybe you guys will show me something the book doesn't.

A container is designed in the shape of an open rectangular solid ( bottom but no top). The container is to hold 1248cc. The base of the container is required to be a sqeare. Find the number of centimeters in the height of the container if its total surface area is to be the minimum possible. Assume no material needs to be wasted in construction. Express your answer as a decimal rounded to the nearest hundredth!!!

Show me your steps, I know the answer I just dont know how to get there!!!

I spoke with someone who's hobby is astronomy and he informed me that over a period of time-like 6 million years or so- that Saturn's rings will fall onto the planet due to Saturn's gravity. He told me the rings are too close to the planet and prevented a moon from forming or Saturn's gravity destroyed a moon. Either way he says the rings at some point will be a thing of the past. Is this true?
