An appliedforce of 6 Newtons acts in the direction of motion of a block of mass 9 Kg, with the mass being pulled across the floor against a frictional force of .6 Newtons. Assume that the block moved the distance 'y' in this process.
* What is the net force on the object?
* How much work does the net force do on the object

A satellite at r(0) =10,000 miles from the center of the earth is given an initial velocity v(0) = 20,000 ft/s in the direction shown(getting further away). Determine the magnitude of the transverse component of the satellites velocity when r=20,000mi.(the radius of earth is 3960mi.)

If a body with a mass of X kg is sliding across a horizontal floor with an initial velocity of Y meters per second and comes to rest after Xmeters, how do you calculate the force of friction that stopped the object?

Consider a force F acting on a particle that moves with a velocity v for F=(6N)i - (5N)j and v = (-5 m/s)i + (4 m/s)j
-What are the magnitudes of F and v?

A car brakes in an emergency, the moment the brakes are first applied is t=0. the car's distance, s, from the point at which the brakes were first applied is given by:
S = -0.1t^3 + 20t + 0.1
(i) Differentiate s to find formulae for the velocityand acceleration.
(ii) Find the time at which the car comes to a stop.
(iii)

Could you please provide a force vs. time graph for the following:
a) a car moves away from the origin with constant velocity
b) car moves tward the orgin with constant velocity
c) moves away from origin is a steady decreasing velocity
d) moves away from the origin, speeds up, then slows down
e) toward to ori

A little red wagon with a mass of 4.60 kg moves in a straight line on a frictionless horizontal surface. It has an initial speed of 10.0m/s and then is pulled 4.0 m by a force with a magnitude of 18.0 N in the direction of the initial velocity.
a) Use the work-energy relation to calculate the wagon's final speed.
b) Calculate

Please help with the following problem.
A force F applied to an object of mass m1 produces an acceleration of 3.00m/s^2. The same forceapplied to a second object of mass m2 produces an acceleration of 1.00m/s^2.
(a) What is the value of m1/m2?.........I understand that a2/a1=1/3 --answer
(b) If m1 and m2 were combine

If the coefficient of kinetic friction between a 12.0 kg crate and the floor is .30, what horizontal force is required to move the crate at a steady speed across the floor? What horizontal force is required if the force of friction is zero?
