SUMMARY
The discussion focuses on calculating the impact speed of an arrow shot from a 30 m high cliff at an initial speed of 25 m/s. Using the conservation of energy equation, Et = Ek + Eg, the calculation yields an impact speed of approximately 34.82 m/s. The methodology involves applying the kinetic energy formula and gravitational potential energy, confirming the accuracy of the result. The conclusion affirms that the calculated impact speed is indeed correct.
