If someone could show me the work with answers that would be great 1) A tightrope walker is practicing. She is balanced on a rope at the exact midpoint of the rope. The tension in the rope is 4000 N, and the mass of the tightrope walker is 64 kg. Consider the left side of the rope. What angle with the horizontal does it make? State this as a positive number in degrees. 2) Two people are pushing their stalled car up a hill with an incline of 3.40°. They are pushing parallel to the surface of the hill. The car's mass is 954 kg. What is the combined force they must apply to keep the car moving at a constant speed up the hill? Ignore the forces of friction and air resistance. 3) A block sits on an inclined plane, which is slowly being raised. The block remains motionless until the angle the plane makes with the horizontal is 22°. At this angle, the block begins to slide down the plane. What is the coefficient of static friction between the plane and the block? 4) A 0.0820 kg pair of fuzzy dice is attached to the rearview mirror of a car by a short string. The car accelerates at a constant rate, and the fuzzy dice hang at an angle due to the car's acceleration. If the dice hang at 9.50° from the vertical as the car accelerates, what is the acceleration of the car? Help on any of these would be great and plz include answers, so i can work back through the problem and understand
