Based on the illustration, how would you relate the maximum horizontal distance attained by the ball to the angle of release as it is being kicked?
A football was projected vertically with an initial speed of 10 m/s at an angle of 30o. To what distance along the horizontal does the football will land from its initial position?
(Note: acceleration due to gravity ag = 9.8 m/s2)

I. Heat is an energy in transit.
II. Heatflows from an object of low temperature to high
temperature.
III. Heat is mostly converted into mechanical energy in
thermodynamics.
IV. Heat increases the temperature of a system with low internal
energy.
