Answer:
vf = 6.724 m/s
Step-by-step 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
