u=100
v=0(as it comes to rest)
t=5
a=v-u/t
a=0-100/5
a=-100/5
a=-20
since acceleration is -20 so retardation is 20
v=0(as it comes to rest)
t=5
a=v-u/t
a=0-100/5
a=-100/5
a=-20
since acceleration is -20 so retardation is 20

Is it a rule that we remove the negative sign when we write acceleration as retardation "

here u equal 100 metre per second t equals to 5sec v equals to 0 use formula v=u+at
I needed the answer, but anyways thank
Thank You
