Sagot :
The average velocity is 127.27 m/s while the initial velocity is 14.55 m/s
According to Newton's law of motion:
s = [(v + u)/2]t
Where s is the distance moved = 1400 m, v is the final velocity = 240 m/s, u is the initial velocity, t is the time taken = 11 s, hence:
1400 = [(240 + u)/2)11
2800 = (240 + u)11
u + 240 = 254.55
u = 14.55 m/s
The average velocity = (v + u)/2 = (240 + 14.55)/2 = 127.27 m/s
Therefore the average velocity is 127.27 m/s while the initial velocity is 14.55 m/s
