Consider the system consisting of two blocks connected by a rope and a pulley. The coefficient of static friction between the ramp and the block on the ramp is 0.36. You may assume the tension in the string connecting the two blocks is the same for all parts of the string. The two arrows define a coordinate system for the block on the ramp. The x axis is parallel to the ramp, the y axis is perpendicular to the ramp. The angle the ramp makes with the horizontal ground is 35 degrees. The block on the ramp has a weight of 13 Newtons. Required:
What is the heaviest weight that can be hung below the pulley without the block on the ramp moving?

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
