Question

A Train is
running with an accelanation 2 m/32
A person is standing of a distance 9m. from
the door of the train. Then the person starts
running and catch the train after 3 see, find
the accelanation of the person​

Answer 1

Answer:

a man is s=9m behind the door of a train when it starts moving ... If 't' is the time after which he catches then, ... Now, the train starts from rest with an acceleration 2 m/s 2.

Answer 2

Answer:

Time taken by the man cover a distance of 9m is T

using second eq of kinematics s=uT+

1

aT

a=2m/s

2

,u=0

⇒9=

1

×2×T

⇒T=3sec

full speed is v

by first equation of kinematic

v=u+aT

⇒v=2×3=6m/s
