SUMMARY
The speed of alpha particles directed towards lead foil with an energy of 2.86 MeV is calculated using the equation v = SQRT(2E/m). The correct calculation yields a speed of approximately 0.078c, but the expected answer is 0.039c, indicating a potential error in the mass used or the interpretation of the energy. The discrepancy arises from the need to account for the mass of the alpha particle, which is twice the mass of a proton. Additionally, relativistic effects may need to be considered for accurate results.
