Answer:
The acceleration from 0 to 4s=velocity/time taken=2/4=0.5 m/s
2
Retardation from 4s to 6s=velocity/time taken=2/2=1 m/s
2
Verified answer
Answer:
to find acceleration we need slope
slope =p/b
= 20/25
=4/5
=0.8m/s^2
it's velocity is constant from the start
=20m/s
to find distance we need to fing the area of the time and velocity enclosed
so distance =20×15
=300m
hope the answers help
