Question

physics chapter motion

Answer 1

Answer:

acceleration=v-u/t

a)acceleration from A to B=- 25/3m/s

=8.333m/s

b) acceleration from B to D=25/4m/s

=6.25m/s

c) total distance covered in first three seconds=25/3m/s

=8.33m/s

d)total distance covered in total time

=25/6m/s

=4.166667m/s

plzzzz mark brainliest answer.

Answer 2

Answer:

1) acceleration of v-t graph is the slope of v-t graph -

25/3 = 8.3333333...m/s^2

2) acceleration from B-D =

-25/3 = - 8.33333333333333...m/s^2

3) distance covered in first three sec = 1/2 *3 *25 = 37.5m

4)distance covered in entire journey is  = 1/2 * 6 *25 = 75 m
