Question

If the speed of a is 3 ft/s up and is increasing at 4 what is the instantaneous speed and acceleration

Answer 1

Sorry I'm in high school.. but according to my physics class, the instantaneous speed is when t (time) is 0, or whatever you'd use (like x).. anyways, when t=0, the instantaneous speed would be 3 ft/s, and the instantaneous acceleration is 0.
