One day, you are driving your car down the highway, and you notice that you are driving well over the speed limit. You apply the brakes of the carapplying a variable stopping force, until the car slows down to a rea sonable speed of 22.4 m/s (50 mph)A computer plots the force versus time for the vehicle and then measures the area under the curve. It is found that the area is - 18.950N . The total breaking time was 5.4 s. Given that the combined mass of you and your car 1sm = 1200 kg how fast were you moving before applying the breaks? What is the average force applied by the road to the car during breaking? (Note: 1Ns=1kg* m/s)

Figure x Part A - Moment due to a force specified by magnitude and endpoints F As shown, a member is fixed at the origin, point O, and has an applied force F, the tension in the rope, applied at the free end, point B. (Figure 1) VE ΑΣΦ ↓↑ vec Mo 0.013,97.9, - 196 Submit The force has magnitude F = 140 N and is directed as shown. The dimensions are x₁ = 0.450 m, x₂ = 1.70 m, y₁ = 2.60 m, and z₁ = 1.30 m. B What is the moment about the origin due to the applied force F?

What is the magnitude of the force acting on a substance if the magnitude of the change in length is (4 cm) and the amount of the constant is (N 625)?

A cube with the dimensions bXbXb with mass m lies on the flat horizontal ground. One the side shown in the figure. The thickness normal to the plane of the figure is b. The cube is subject to the earth's gravity and the friction coefficient between the cube abd the ground is mu. Express your answer in terms of the given variables. What is the minimum force required to produce sliding? What is the minumum force required to produce tipping of the cube? Assume the cube is rotating about O. Impulsive horizontal loading L is applied on the edge B such that force F(t) is applied during the very short time delta t: where L= the integral from zero to delta t of F(t)dt. What is the minimum value of the impulse for which the cube tips over and falls on side OA.
