Step-by-step explanation:
v = final velocity
u = initial velocity
s = Distance
a = Acceleration
__________
✨ First case,
v = 0 m/s
u = 10 m/s
s = 20 m.
➡️ v^2 = u^2 + 2as
Or, 0 = 100 + 40a
Or, a = - 100 /40 = - 5/2.
.°. a = - 5/2 m/s^2
___________
✨Second case,
v = 0 m/s
u = 20 m/s
a = - 5/2 m/s^2
➡️ v^2 = u^2 + 2as
Or, 0 = 400 - 5s
Or, s = 400/5 = 80.
.°. The stopping distance will be 80 m.
