A force F with arrow= (6xi+ 5yj), where F with arrow is in newtons and x and y are in meters, acts on an object as the object moves in the x direction from the origin to x = 5.32 m. Find the work W = the intergral of F with arrow · dr with arrow done by the force on the object.
A Force F= (6xi+ 5yj), where F is in newtons and x and y are in meters, acts on an object as the object moves in the x direction from the origin to x = 4.69 m. Find the work W = integral (F
A force acting on a particle moving in the xy-plane is given by F = (2x3y4i+x2y3j), where F is in newtons and x and y are in meters. The particle moves from the origin to a final position having coordinates x=5.00 m and y = 5.00 m as shown in the figure. Calculate the work W = F(r) dr done by F on the particle as it moves along a) The purple path b) The red path
A force F = (3xi - 2xyj) N acts on an object as the object moves in the .x direction origin to .v 5.00 m (no motion in v-axis). The object has a mass m = 5.00 kg. Find the work done on the object by the force F. lf the object starts from rest, what is the final speed of the object at x = 5.00 m.?
A force F = (3yi -2x2yj) newtons acts on a object that moves in a straight line directly from the origin to the point p = (2i + 4j) meters. How much work does the force do on the object during this process?
A force F = (3.10N) î +(7.20N)ị + (7.30 N) k acts on a 6.30 kg mobile object that moves from an initial position à ; = (6.60m) î + (5.40 m)ſ +(3.80 m) Ê to a final position of ds = (6.20m) î +(7.70 m) Î + (3.30 m) î in 8.50 s. Find (a) the work done on the object by the force in the 8.50 s interval, (b) the average power due to the force during that...
The force in newtons acting on a 4kg mass is f=12x^3-12x^2+16x+14 where x is in meters. F is oriented in the x direction and acts on the 4kg mass from x0=0 to xf=3m. If inittiallly at rest and all of the work of f is conserved, find the velocity of the 4 kg mass at xf=3m. report results in m/s
Assume the force (in Newtons on an object is given by the function of position F(x)-2 xA3+16, where x is the position (in meters). The object has a mass of 2 kg, what is the work (in Joules) done on the object from x-Orm to ? work done = What is the work (in Joules) done on the object from x=2 m to x=4 m? what is the work (in Joules) done on the objet from x=0 m to x=4...
10. A force ? 1 of magnitude 6.00 newtons acts on an object at the origin in a direction θ = 30.0° above the positive x axis. A second force ? 2 of magnitude 5.00 newtons acts on the object in the direction of the positive y axis. a. Find graphically the magnitude and direction of the resultant force ? 1 +? 2. (Do this on graph paper or engineering paper. Measure the resultant and the angle it forms.) b....
