Answer:
Whenever you see the delta symbol infront of another, it always represents change. In other words:
Δu = u_f - u_i
- u_i means "initial velocity"
- u_f means "final velocity"
And in general, ΔX means Xfinal - Xinitial
a. Change in velocity
The delta symbol in the velocity equation represents the change in velocity.
[tex]\triangle V= V_f-V_i[/tex]
where,
[tex]\triangle V[/tex]= change in velocity
[tex]V_f[/tex] = final velocity
[tex]V_i[/tex] = initial velocity
Thus, option a is correct.
