Answer:
3.5m/s2
Explanation:
u=54km/hr
=54*5/18
u =15m/s
s=ut+1/2at2
1000=15(20)+1/2a(20*20)
1000-300=1/2a(400)
700*2=400a
a=1400/400
=3.5m/s2

Answer:
Here is your answer
Explanation:
Distance = 1 km - 1000 m
Time = 20 seconds
Speed = 15m/s
Accelaration = Final Velocity - Initial Velocity/ Time
Accelaration = (15 m/s - 0 m/s) / 20 Seconds
Accelaration = (15 m/s) / 20 Seconds
Accelaration = 0.75 ms^2
