3 a is the ans i think so ....
Answer:
The branch of physics that is most relevant to football is mechanics, the study of motion and its causes.
Explanation:
When the ball leaves the punter's foot, it is moving with a given velocity (speed plus angle of direction) depending upon the force with which he kicks the ball. The ball moves in two directions, horizontally and vertically. Because the ball was launched at an angle, the velocity is divided into two pieces: a horizontal component and a vertical component.
Answer:
75.645 J
Explanation:
The kinetic energy is related to the mass and velocity by the formula ...
KE = 1/2mv²
For the given mass of 0.045 kg, and velocity of 41 m/s, the kinetic energy is ...
KE = 1/2(0.045 kg)(41 m/s)² = 75.645 J
__
The unit of energy, joule, is a derived unit equal to 1 kg·m²/s².
the state of being thick, sticky, and semifluid in consistency, due to internal friction.
