Question

A train running at the speed of 120 kilometre per hour is approaching a station .Driver applies break just 200 before the station to stop it. Find the acceleration of train​

Answer 1

Step-by-step explanation:

Given:

Velocity = 120 km/h

Time= 30 sec

Change km/h into m/sec

[ 1km= 1000m , 1hr= 3600sec]

velocity = (120*1000)/ 3600 = 100/3 m/sec

Velocity = 100/3 m/sec

Distance= velocity *time

Distance= (100/3) *30= 1000 m

Answer

Distance = 1000m

Answer 2

Hey user here is Answer

Solution

according to question

given that

v=120 km/h

s=200 km

a=?

u=

using this formula

v^2=u^2+2as

(120)^2=0^2+2×a×200

400a=14400

a=14400/400

a=144/4

a=36 m/s^2. Answer.
