Students are using an air rocket to investigate the relationship between
force and an object's motion. Students pump air into the rocket and let the
rocket go. The compressed air pushes the rocket upward. In order to
change the amount of force acting on the object what would students
need to make different?*
-Cone
Rocket
Pump
Fins
Hose
The height of the rocket.
O The amount of air pumped into the rocket.
O The length of the hose attached to the rocket.
The distance the rocket travels

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?
