Could you explain that please?You can find the initial speed in the vertical direction.
Vertical displacement is 15m, and Gravity due to acceleration is 9.8 m s^2Try to find what is known in the vertical direction.
Correct but acceleration is negative if we choose upward direction as positive.Vertical displacement is 15m, and Gravity due to acceleration is 9.8 m s^2
I think that you mean the initial (vertical) speed.Before I calculate the final speed, I have to get t, correct?
Yes, I did.I think that you mean the initial (vertical) speed.
Sorry, I'm having a hard time getting my head round this.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.
