A 20.4 kg box initially at rest is pushed 4.08 m along a rough, horizontal floor with a constant applied horizontal force of 97.0653 N. Acceleration of gravity is 9.8 m/s^2.

If the coeficient of friction between the box an the floor is 0.434, find the work done by the friction in units of J.

Also, Find the final speed of the box in units of m/s.

Help!

I need a way of randomising sample files - I mean I need some kind of formula or table which would allow me to select some files from a bunch in a random way which would stand up to scrutiny.
Do you know of any way of doing this with a randomising table or programme or something?
Sorry I'm not clear about this - I know what I'm looking for, but don't know how to explain it very well.
Any help would be much appreciated.

A time varying net force acting on a 6 kg particle causes the object to have a displacement given by:
x = a + b t + d t^2 + e t^3
where:
a = 2.1 m,
b = 1 m/s,
d = -2.3 m/s^2,
e = 0.97 m/s^3

with x in meters and t in seconds. Find the work done on the particle in the first 2 s of motion. Answer in units of J.

My kids were given a used Meade Infinity 114/900 EQ1-B, with no product manual... I've already been to the Meade website and found nothing on this particular model. I would love to learn how to use it, so that my kids can actually view something rather than it just collect dust. If any one could be of any assistance, I would greatly appreciate it! Thanks in advance.
