There is a circular slope that a skier is going down. He is at the top. If he goes just fast enough to start down the slope, at what angle to the center of curvature does the skier go airborne? I'm not sure if its asking for an exact angle or what. Any help or shove in the right direction is...

If I pull a box at a small horizontal angle (say 5 degrees) with a constant force up the slope, and pull another box with the same magnitude of force (at say 60 degrees) up, will the two boxes have the same acceleration, or will one box accelerate faster? If so, which one is accelerating...

If I'm finding the slope of the line of average balance mass(g) vs. total mass (g), should the units for slope be grams? or does it not have units? I know it should be g/g but would that cancel out or stay grams? Sorry if that's confusing. Thanks.

Hey guy's just found this forum, seems pretty interesting, but I've been nested in my bedroom trying to figure out one little thing that miffed me off, I did it in A level physics a while back and remember understanding it completely. Just to make the question a little easier I'd like to...

A ski jumper acquires a speed of 111.4 km/hr by racing down a steep hill. He then lifts off into the air from a horizontal ramp. Beyond this ramp, the ground slopes downward at an angle of q = 45°. Assuming the skier is in free-fall motion after he leaves the ramp,at what distance down the slope...

In this lab, I'm supposed to find the average slope between a charging and discharging capacitor. For the slope of charging and for the slope discharging I used the basic formula y2-y1/x2-x1 choosing arbritary points on both lines. Charging slope = 4.6/-15, and discharging slope = 3.48/-57. Now...

If I take an infinitely long, thin wing and measure its lift curve slope I should get 2pi. Now if I take a 1/2-wing and fit 1 end to a plate and test it in a wind tunnel, it should simulate the flow around a full span wing, am I wrong? Therefore measuring lift and working out the CL values...

I started running a few weeks back and I want to know if I'm improving speed-, distance- and duration-wise. I have a set of data like these (this is bogus data), currently in Excel: 15 13 16 17 15 15 14 17 17 and I want to know if these numbers get larger with time. How would...

With a given inclination of a 130 degrees. and up in the left corner it says -1 I have no idea how to do this, any idea?

Slope of an x vs t plot question...Help please.. The slope of an x vs t plot is NOT acceleration right? The slope of a point on the x axes is just the velocity at that point in time, right? Thanks for any help you can give me.

Hello all, I've searched and browsed and I haven't found anyone else that's asked this question, so I will ask it here. A cannon point at a fixed angle of 30° is placed on a slope of 12° and fired uphill at an initial velocity of 30 m/s. What is its range? I thought about making the...

Derive the slope of a track where a sphere having frictional coefficient u maintains constant velocity v.

I haven't done this yet (Yeah, I know I should have at my age but the last time I did it in class with proper practice was at least 3 years ago so, thankfully, this will be like review.) so I wanted to check my answer before turning it in... If we were to estimate the horizontal distance for...
