Part CLearning Goal:A box of mass 3.0 kg slides down a rough vertical wall. The gravitational force onthe box is 29.4 N. When the box reaches a speed of 2.5 m/s, you start pushingon one edge of the box at a 45° angle (use degrees in your calculations throughoutthis problem) with a constant force of magnitude Fp = 23.0 N, as shown in (Figure 1). There is now a frictional force between the box and the wall of magnitude13.0 N. How fast is the box sliding 3.0 s after you started pushing on it?Find the box's speed of at 3.0 s after you first started pushing on it.▸ View Available Hint(s)vf = 2.6 m/sFigure1 of 145°14SubmitPrevious AnswersReviewCorrect>Assuming that the angle at which you push on the edge of the box is again 45°, with what magnitude of force Fp should you push if the box were to slide down the wall at a constant velocity? Notethat, in general, the magnitude of the friction force will change if you change the magnitude of the pushing force. Thus, for this part, assume that the magnitude of the friction force is f = 0.516F.▸ View Available Hint(s)Part DΕΠΙ ΑΣΦwwwww?FpSubmitN

Newton's first law states that: Group of answer choices Ia. n the absence of any net force acting on it, a mechanical system is necessarily at rest. b. In the absence of a non-zero net force acting on it, a mechanical system keeps moving in the same direction at the same speed (including the case v=0). c. For any pair A/B of objects interacting with one another, the force of A acting on B is the equal-opposite of the force of B acting on A. d. The rate of change of the velocity of a system is proportional to the net force acting on it.
