The efforts applied are 320Nm.
What is work or effort?
Work is when we apply force on body and displacement occur are called work .
W= Fs
where F is force and s is displacement .
displacement is 2-1.6
. = 0.4m
By applying the value in formula
We have given F =800N
W= 800× 0.4
W= 320Nm.

Given:
u(initial velocity)=0
a=5.54m/s^2
v(final velocity)=2 m/s
v=u +at
Where v is the final velocity.
u is the initial velocity
a is the acceleration.
t is the time
2=0+5.54t
t=2/5.54
t=0.36 sec
