2. Which member of the following...
Okay I don't know how I got that second one either.
I kept plugging in the numbers and got that second answer.
For some reason, after I read Dweirdo's post, I plugged it in again and this time it worked.
Don't know what I did back then but thank you very much!
Homework Statement
A 11 kg satellite has a circular orbit with a period of 1.0 h and a radius of 4.9 × 10^6 m around a planet of unknown mass. If the magnitude of the gravitational acceleration on the surface of the planet is 41 m/s^2, what is the radius of the planet?
The attempt at a...
Homework Statement
A uniform circular disk whose radius R is 14.3 cm is suspended as a physical pendulum from a point on its rim. (a) What is its period? (b) At what radial distance r < R is there a pivot point that gives the same period? (give answer in cm)

Oh, I see. That makes a lot of sense. Then I just plug it in and I got 1170kg/s. My confusion with the capital and lower t's got me mixed up. Thankyou very much. =]
Homework Statement
The suspension system of a 2200 kg automobile "sags" 14 cm when the chassis is placed on it. Also, the oscillation amplitude decreases by 55% each cycle. Estimate the values of (a) the spring constant k and (b) the damping constant b for the spring and shock absorber system...
Homework Statement
At the instant of Fig. 11-42, a 6.60 kg particle P has a position vector \stackrel{\rightarrow}{r} of magnitude 3.80 m and angle θ1 = 42.0° and a velocity vector \stackrel{\rightarrow}{v} of magnitude 9.70 m/s and angle θ2 = 33.0°. Force \stackrel{\rightarrow}{F}, of...
Homework Statement
The wheel in Fig. 10-29 has eight equally spaced spokes and a radius of 30 cm. It is mounted on a fixed axle and is spinning at 3.6 rev/s. You want to shoot a 26-cm-long arrow parallel to this axle and through the wheel without hitting any of the spokes. Assume that the...
Yes, so.. er this is where I get confused.
Should I just stick the acceleration in x and y into the formula
x = x0 + .5at^2 ?? with the x being the 0.742 and then 2.75 to find the final x,y?
It sounds right but I just seem to doubt it.
Homework Statement
A big olive (m = 0.051 kg) lies at the origin of an xy coordinate system, and a big Brazil nut (M = 0.56 kg) lies at the point (0.81, 3.0) m. At t = 0, a force Fo = (2.6 + 1.7) N begins to act on the olive, and a force Fn = (-4.4 -3.4) N begins to act on the nut...
