Dear pallavi

acceleration of ship a=5*104 N/ 3*107 KG

                               =5/3 *10-3 m/sec2

speed of the ship after movieng 3 m 

v2 =u2 +2aS

    =0 +2* 5/3 *10-3   * (3)

    = 10-2

v=.1 m/sec

M=3*10^7
F=5*10^4 N
S=3m
U=0
V=?
We know,
F=M.A
 
5*10^4=3*10^7*a
a=5/3*10^-3
We know,
 V²=U²+2as
V²=2*5/3*10-³ .3+0²
V²=10*10-³
V=√10²
V=.1m

Dear Student,
Please find below the solution to your problem.

acceleration of ship a=5*104 N/ 3*107 KG
=5/3 *10-3 m/sec2
speed of the ship after movieng 3 m
v2 =u2 +2aS
=0 +2* 5/3 *10-3 * (3)
= 10^-2
v=.1 m/sec

Thanks and Regards
