i don't understand what is concerved? heeeeeeeelllp? lol

Homework Statement a mouse is rinding on the rim of a 2.0kg wagon wheel that rotates freely in a horizontal plane at an angular frequency of 1.00 revs/sec. after riding there for a while, the mouse runs into the center, axis, of the wheel. the mass of mouse is 0.1kg and assume that all of...

so if work is mg*distance then would the work be 2.0kg*10m= 20kgm?

Homework Statement find the speed of a satillite in orbit 1000km above the Earth's surface. mass of Earth 5.98*10^24kg mass of satellite = 50.0kg radius of earth=6.38*10^6m Homework Equations so i used V= square root of G*mass of earth/r The Attempt at a Solution V= square root...

ok i don't know if this is a type o or not but yes the acceleration due to gravity for the moon is ~1.62m/s^2 but in this prob, the radius is given @ 1.76*10^6 thus giving an acceleration due to gravity @ ~1.58m/s^2 and in using the above formula you gave me, X=Vot+.5at^2 is Vo my...

Force Problem! Homework Statement a ball of mass 2.0kg is dropped from a height of 10m. the speed of the ball is measured as 12.5m/s just before it hits the ground. what was the work done against air friction during this fall? Homework Equations The Attempt at a Solution totally...

acceleration due to gravity help! Homework Statement PROB: How long would it take for a mass of 1kg to fall a distance of 2m to the surface of the moon? Homework Equations G=6.673*10^-11 Nm^2/kg^2 R of moon = 1.76*10^6m m of moon = 7.35*10^22kg The Attempt at a Solution i started by...
