Please refer to attachment for diagram:
1) During what time interval is the motion of the body accelerated:
The body is accelerated between A to B[ 0 to 4 unit] and c to d [8 to 10 unit ]body is decelerating .
2)Find the acceleration in the time interval mentioned in part 'a'.
a= v-u/t
=30-0/4= 7.5 m/s²
3)What is the distance travelled by the body in the time interval mentioned in part a?
s=ut+1/2 at²
=0x4 + 1/2 x 7.5 x 4²
=75x 4 x 4/ 2x10
=75 x4/5
=15x4= 60 m
