When an object moves in a straight line with uniform acceleration from a certain moment, its initial velocity is known to be four meters per second, and its acceleration is two meters per second

When an object moves in a straight line with uniform acceleration from a certain moment, its initial velocity is known to be four meters per second, and its acceleration is two meters per second

v0=4m/s^2,a=2m/s^2
At the end of 2S, v = V0 + at = 4 + 2 * 2 = 8m / S
