Hi everyone,
I am just starting to get into using physics and calculus, and have just been doing my own experiments to understand the concepts etc better.
I have formed an equation for displacement against time for a projectile and have differentiated it to get equation of velocity, then differentiated that to get equation of acceleration.
Equation: a=14.28t-17.56 (t=time in seconds)
I also know that at t=1.23, v=0; intitial v=10.80m/s; total displacement=8.86m at t=2.46; a due to g=9.81m/s/s.
I would just like to know how to work out the vertical velocity, as the decceleration is greater than 9.81 (I think).
I have spent the last few hours looking around the internet, but I'm not really sure what I'm looking for.
Thanks in advance.
