Calculation of Horizontal Velocity, Initial Vertical Speed

Click For Summary
SUMMARY

The discussion focuses on calculating horizontal velocity, initial vertical speed, angular launch speed, launch angle, and maximum height for an object with a mass of 7.3g projected over a distance of 24.5m. Key equations of motion are provided, including V=d/t, v = u + a t, and v^2 = u^2 + 2 a s, which are essential for solving the problem. The assumption of no air resistance is crucial, as it allows for a constant horizontal velocity. Participants emphasize the importance of correctly applying the formulas to both vertical and horizontal components of the initial velocity.

Remember the basic equations of motion for particles like this

[tex] v = u + a t[/tex]

[tex] s = s_0 + u t + (1/2) a t^2[/tex]

[tex] v^2 = u^2 + 2 a s[/tex]

where v is the final velocity, u is the initial velocity, s is the displacement, a the acceleration and t the time.

Also remember that you are going to be assuming no air resistance, so horizontal velocity will remain constant.

Applying these formulae to vertical and horizontal components of the initial velocity should get you all of those

another formula that may come in handy is...
2a∆y=V²-Vo²

where Vo=initial velocity.
since it includes horrizontal motion, be sure to use the right components when pluging in the variables, expecially for velocity. good luck
