Question

A train accelerates from 10m/s to 15m/s. Then find the acceleration and distance travelled by car.

Answer 1

hello friend
ur query is incomplete ..u have not mention the time ..
m giving u the formula :
acceleration = final velocity - initial velocity / time
here initial velocity is 10m/s and final velocity is 15m/s 
so, 15 m/s - 10m/s / t ( which u have not mention)
= 5  / t
and the answer will written as x m/s ²
hope u got me

Answer 2

Hello freind !!
Given -

Acceleration = ?

Distance travelled = ?

initial velocity , u = 10 m/s

Final velocity , v = 15 m/s

Time = 10 sec

we know
A = V- U / t
= 15 - 10 / 10
= 5 / 10
= 1/2 m/s^2

From 2nd eq of motion we have

s = ut + 1/2 at^2

= 10 ×10+ 1/2 ( 1/2 ) × 100

= 100 + 50 × 1/2

= 100 + 25

= 125 m

hence the distance travelled by the train is 125 m
