The discussion revolves around applying the impulse-momentum theorem to determine the time it takes for a stone to accelerate from an initial velocity of 4.8 m/s to a final velocity of 10.7 m/s while falling straight down. Participants express uncertainty about how to find the time with only the initial and final velocities provided.
The discussion is ongoing, with participants exploring different interpretations of the problem. A hint regarding the consideration of acceleration has been offered, but there is no explicit consensus on how to proceed further.
Participants are grappling with the relationship between time, velocity, and acceleration, noting the challenge of finding time without direct information about acceleration or the time interval itself.
I am going to consider this an attempt at a solution, and offer a hint: You also know the acceleration.Raimuna said:I really don't get the question. How could we find the time in second if we only know the initial and final velocity.
