Answer:
The work W done by the net force on a particle equals the change in the particle's kinetic energy KE: W=ΔKE=12mv2f−12mv2i W = Δ KE = 1 2 mv f 2 − 1 2 mv i 2 .

Answer:
The work W done by the net force on a particle equals the change in the particle's kinetic energy KE: W=ΔKE=12mv2f−12mv2i W = Δ KE = 1 2 mv f 2 − 1 2 mv i 2 .
You want to prove that the equation for work in terms of the change in kinetic energy of an object is:
W = ΔKE. or.
W = KEf− KEi where. ...
W = mad. where. ...
a = (vf − vi)/t. Multiply both sides of the equation by t and divide by a:
t = (vf − vi)/a. ...
d = t(vf + vi)/2. ...
d = (vf − vi)(vf + vi)/2a. ...
2ad = v2f − v2i
Hope it helps you keep smiling :)
