A car traveling at 3.6 m/s accelerates at the rate of 0.71 m/s2 for an interval of 4.4 s. Find vf. Incorrect: Your answer is incorrect. m/s

vf = 6.724 m/s

Explanation:

Velocity: This an be defined as the rate of change of displacement. Velocity is a vector quantity, because it can be represented both in magnitude and direction. The S. I unit of velocity is m/s.

From newton's equation of motion,

vf = vi + at ... Equation 1

Where vf = final velocity, vi = initial velocity, a = acceleration, t = time.

Given: vi = 3.6 m/s, a = 0.71 m/s², t = 4.4 s.

Substitute into equation 1

vf = 3.6+0.71 (4.4)

vf = 3.6+3.124

vf = 6.724 m/s

Hence, vf = 6.724 m/s
