If she were to use the mattress as a trampoline losing contact with it for part of each cycle. What minimum amplitude of oscillation does she need.
Points A and B have electric potentials of 257 V and 129 V, respectively. When an electron released from rest at point A arrives at point C its kinetic energy is KE1, What is the electric potential at point C
Even as exploring a sunken ocean liner, principal researcher found the absolute pressure on the robot observation submarine at the level of the ship to be about 413 atmospheres. The density of seawater is 1025kg/m^3.
Gold, which has a density of 19.32 g/cm3, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber, If a sample of gold with a mass of 2.477g, is pressed into a leaf of 4.116 ?m thickness, what is the area (in m2)..

At t = 5.0 seconds, the cheetah is standing still, having knocked over the gazelle. Illustrate what is the average acceleration of the cheetah from t = 0 to t = 5.0 seconds?
Ricardo and Jane are standing under a tree in the middle of a pasture. An argument ensues, and they walk away in different directions. Ricardo walks 24.0 in a direction 60.0 west of north. Jane walks 12.0 in a direction 20.0 south of west. They then ..
Since the vehicles stick together after the collision and take the direction of the large truck (greater momentum), I guessed that the small car would have a greater change in kinetic energy.
