To what extent was Aristotle’s model of falling bodies correct? How was it wrong?
An adventurous archaeologist crosses between two rock cliffs by slowly going hand-over-hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Figure 1). The rope will break if the tension in it exceeds 2.55×104 NN , and our hero's mass is 87.6 kgkg1. If the angle between the rope and the horizontal is θθtheta = 11.1 ∘∘, find the tension in the rope?2. What is the smallest value the angle θθ can have if the rope is not to break?

What is Newton's 3rd law of motion? Examples needed. Thanks
answers to both question s While we think of weight as "mass", it is actually the pull of gravity on the object. For example, 4.5 kilograms (kg) near Earth is pulled with a force of about 45 newtons, that is, the same force we call "10 pounds" here in the U.S. where the metric system is not as familiar. Now put a 10 lb box at rest on a flat table. What is the total force on the box? mg That's the force of gravity downward on the box. 0 There is no net force on the box. The frictional force F which is μ mg N That's the normal force of the table pushing up on the box. How fast will an object be falling if dropped from rest and allowed to fall for 94 seconds? Use g = 10 m/s2 and give your answer in m/s
