so i would find the y and x components for each of the forces then add them up and use Pythagorean theorem then multiply that by the distance?
For the angle of F2 should it be 270-51.6=218.4 degrees and should angle of F1 be 180 degrees?
1. Figure 7-30 shows an overhead view of three horizontal forces acting on a cargo canister that was initially stationary but that now moves across a frictionless floor. The force magnitudes are F1 = 2.28 N, F2 = 4.54 N, and F3 = 8.24 N, and the indicated angles are θ2 = 51.6° and θ3 = 35.8°...
1. Define this method so that it adds the Strings in inputto an initially empty LRStruct<String> so that they appearin the same order. Example: if input contains "a", "b" and "c", in that order, the returned list must contain "a", "b" and "c", in that order.
LRStruct Class...
1. In Fig. 6-50, block 1 of mass 4.0 kg and block 2 of mass 6.6 kg are connected by a string of negligible mass and are initially held in place. Block 2 is on a frictionless surface tilted at θ = 38o. The coefficient of kinetic friction between block 1 and the horizontal surface is 0.18. The...
Well here's a hint that I get from Wiley Plus
Write Newton's second law for forces along a vertical y axis. Is the (centripetal) acceleration up or down? What is the gravitational force? (For safety, the car has wheels both above and below the track.)
So it should look like this?
(1290(9.32)/20)+(1290*9.8)=18221N
(1290(182)/20)+(1290*9.8)=33540N
Sorry if I'm being annoying I'm on my last attempt for my online homework so I want to make sure it's correct before I submit it.
1. A roller-coaster car has a mass of 1290 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 20 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative sign for the downward direction) FN on the car...
