Answer:
I believe whale fossils were found.
To obtain the vertical component of the velocity, it is necessary to multiply the velocity at this time by sin 45 degrees. Since the velocity is not given, it must be solved first by dividing the distance by the time. To show this:
Velocity = distance / time
Velocity = 30 m / 4s
Velocity = 7.5 m/s
Vertical velocity = 7.5 sin 45
Vertical velocity = 5.3 m/s
Answer:
the ability to do work.

in other words "the potential for causing changes" or "energy is the cause of any change" or "a work that a certain force *eg: gravitational* can do.

First let us examine our options. For B, the law of inertia state that an object will keep on moving unless acted upon an external force. And I am thinking this is not the appropriate answer here. Also for C momentum and mass are not the same. Momentum is energy. Momentum cannot be converted to mass. A is the answer since momentum. When the ball hits the box, the box will move and decreases the velocity of the rock. Here momentum is transferred. <span />
