Webin the video. He started with the formula: vi + (delta t) (a) = vf 5 + (4s) (2 m/s^2) = vf 5 m/s + 8 m/s = vf 13 m/s = vf So 8 m/s = (delta t) (a) = vf - vi = delta v This 8 m/s is the change in velocity (v increased by 2 m/s every second, for 4 seconds). WebIf the car's speed is instantly reduced to 10 m/s directly at the start of the 2 minutes, then the car will have travelled: 10 m/s x 2 x 60 s = 1200 m. If however the car continued at 25 … WebThinking about velocity, speed, and definite integrals. Say a particle moves in a straight line with velocity v (t)=5-t v(t) = 5−t meters per second, where t t is time in seconds. When the velocity is positive it means the particle is moving forward along the line, and when the velocity is negative it means the particle is moving backwards. chrystal collins mugshot jackson kentucky
