Afootball game begins by flipping a penny to decide which team will get the ball first. the 5.25 g penny has a speed of 3.27 m/s just before it hits the ground. if half of the increase in the internal energy of the ground and penny is transferred to the penny’s internal energy, by how much does the penny’s temperature increase after impact? assume that the penny’s temperature increases by 1.00° c as 2.03 j are added to its mass.

Ultra-high temperature (uht)

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
