Question

A train acceleration at 9 m/s squar for 5s .if its initial velocity is 5m/s .what its final velocity ?

Answer 1

Explanation:

uniform acceleratrion of 5 m/s2  

u = 5 m/s  

t = 5 s  

a = 5 m/s2  

by second equation of motion

s equals space u t plus 1 half a t squared

equals space 5 space cross times 5 space plus space 1 half left parenthesis 5 right parenthesis space cross times 5 squared

equals space 25 space plus space 62.5

equals 87.5 space m

Distance travelled by object moving with 5 m/s in 5 s when acceleration is 5 m/s2 is 87.5 m
