Question

pls answer with working​

Answer 1

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

Answer 2

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
