A body of mass 0.4 kg starting at origin at t = 0 with a speed of 
in the positive x-axis direction is subjected to a constant F = 8 N towards negative x-axis. The position of the body after 25 s is:
Text Solution
Verified by ExpertsThe correct answer is:
A
: Here
Mass of the particle 
F = -8N
(minus sign for direction of force
Acceleration, 
The position of the body at any time t is given by
The position of the body at t=0 is 0, therefore 
Position of the body at 
Here
