Hawkeye, surrounded by alien Chitauri, fires a concussive arrow into the ground. This creates a groundwave that will hopefully knock down the aliens. There are fractions of a second before Hawkeye is shot by the Chitauri. How could he make the ground wave travel faster?
Any of the answers would work.
since v = f * λ , he needs to produce a greater wavelength
Since v = f * λ, he needs to produce a higher frequency
The only way to change the velocity of a wave is change the medium it is traveling through

A ball of mass m is moving to the right with a velocity v1 and hits an identical ball (mass m) at rest. After they collide, what happens to each ball assuming an elastic collision?
the first ball comes to rest, while the second ball moves to the right with velocity v1
they both come to rest
they both move to the right with a velocity less than v1
they bounce off each other and move in opposite directions with a velocity equal to half v1
The Hulk often jumps very high and a great distance in order to travel quickly. While the Hulk jumps up, does the Earth gain momentum in the opposite direction?
Yes, the earth recoils, like a rifle firing a bullet, with a change in momentum equal to and opposite to that of the Hulk's.
No
Yes; because of its much larger inertial mass, however, the change in momentum of earth is much lass than that of the Hulk's body.
It depends.
