Question

What is the final velocity of a runner who is accelerating at 2 feet per second squared for 3 seconds with an initial velocity of 4 feet per second

Answer 1

a= 2 ft/s^2 t=3 s vi=4 ft/s vf=? One can use the kinematic equation: vf=vi+at vf=(4 ft/s)+(2 ft/s^2)(3 s)= (4 ft/s)+(6 ft/s)=10 ft/s
