Question

A football game customarily begins with a coin toss to determine who kicks off. The referee tosses the coin up with an initial speed of 6.00 m/s. In the absence of air resistance, how high does the coin go above its point of release

Answer 1

Answer:

The coin travels 1.8348 meters above its point of release.

Explanation:

Initial speed = 6 m/s (Assumed vertical speed as not stated in question)

Final Speed = 0 m/s    (at the highest point in air)

Acceleration due to gravity = -9.81 m/s^2

Equation of motion used:

$(V_f)^2 - (V_i)^2 = 2 *a * s$

$0^2 - 6^2 = 2 * (-9.81) * s$

s = 1.8348 m

Thus, the coin will travel 1.8348 meters up to its highest point in the air.
