A particle is acted upon by a net force F=F0e-kx, where F0 and k are constants. If the particle has velocity equal to zero at x=0, then the maximum kinetic energy that the particle can attain is:. 1. F0/k
2. F0/ek
3. kF0
4. (kF0)2
5. kekF0

F₀ /k .

Explanation:

Force is variable

F=F₀

kinetic energy = work done by force

= ∫ F dx

= ∫F₀ dx

= F₀ / -k

E =  F₀ / -k

=  -F₀ /(k )

For maximum E , should be minimum ,

is minimum for x = 0

maximum value of E = F₀ /k .

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
