Dear Mantra
 
As we see
The forward acceleration produced due to force F= ma or a= F/m, here F= 770 N, m= 350 Kg a= 2.2 m/s

from second law of motion f=ma
f= 7.70*102 N
m= 350 kg
puttong these values we get
770= 350 * a
a= 2.2 m/s2
from first equation of motion:-
v= u + at
12= 0 + 2.2t
on solving we get
t= 5.45s
from ird equation of motion
v2 – u2= 2as
0 – 144=2 * a * 50
-144=100*a
a= -1.44 m/s2
