please tell
A cyclist is travelling at 15 m sl. She applies brakes so that she does not collide with a wall 18 m away,
What deceleration must she have ?
1. Draw a velocity-time graph to show the following motion :
A car accelerates uniformly from rest for 5 s; then it travels at a steady velocity for 5 s.
2 The velocity-time graph for part of a train journey is a horizontal straight line. What does this tell you about
(a) the train’s velocity, and (b) about its acceleration ?​

sorry it’s of science I accidently clicked maths

  1. Answer:

    6.25m/s

    2

    Step-by-step explanation:

    Initial velocity, u=15m/s

    Final velocity, v=0m/s

    Distance, s=18m

    Acceleration, a=?

    Using relation, v

    2

    −u

    2

    =2as

    0

    2

    −(15)

    2

    =2a×18

    −225=36a

    a=

    36

    −225

    =−6.25m/s

    2

    So, deceleration is 6.25m/s
