The discussion revolves around a projectile motion problem, specifically focusing on determining initial and final velocities, vertical displacement, and the time of flight. Participants are exploring the equations of motion relevant to vertical motion under gravity.
The discussion is active with participants sharing insights on how to approach the problem. Some have provided guidance on identifying known values and equations, while others express uncertainty about the correct equations to use for finding final velocity and time.
Participants note that vertical displacement is 15m and that gravity is -9.8 m/s² when considering upward direction as positive. There is an ongoing exploration of the implications of these values on the calculations needed.
grzz said:You can find the initial speed in the vertical direction.
grzz said:Try to find what is known in the vertical direction.
Correct but acceleration is negative if we choose upward direction as positive.MrRandom66 said:Vertical displacement is 15m, and Gravity due to acceleration is 9.8 m s^2
I think that you mean the initial (vertical) speed.MrRandom66 said:Before I calculate the final speed, I have to get t, correct?
grzz said:I think that you mean the initial (vertical) speed.
grzz said:If you know the initial and final vertical speeds, and the vertical distance you can find the time which is the quantity that you originally wanted to find.
