SUMMARY
The speed of a body on a smooth horizontal surface, where the mass decreases exponentially with a disintegration constant λ, can be described by the equation v(t) = u(1 - e^(-λt)). This equation is derived from the principles of conservation of momentum, particularly in the context of rocket motion. The discussion emphasizes the importance of understanding logarithmic and exponential functions to solve the problem effectively. The initial velocity of the body is zero, which simplifies the calculations.
