- Wait patiently for a helper to come along.
- Once someone helps you, say thank you and close the thread with:
+close
- Feel free to nominate the person for helper of the week in #helper-nominations
- Do not ping the mods, unless someone is breaking the rules.
- If you're happy with the help you got here, and the server overall, you can contribute financially as well:
divide the total distance into 3 parts:
a = distance covered while the car accelerates
b = distance covered while speed is constant
c = distance covered while car decelerates
maximum speed would be the speed of the car when it's speed was constant, or it's final speed after undergoing acceleration
it accelerated at the rate of 2ms^(-2) for 6s ryt?
so use
v = u + at
you have a=2ms^(-2) , t=6s , u=0ms^(-1) (car starts from rest)
and for the distance a just use s=ut+1/2 at^2
you have u, a and t
distance b is just whatever speed you got in a * 30s
for distance c
you have u as whatever speed you got in a
v as 0
t as 5
and you know $a = \frac{v-u}{t}$

and you know $a = \frac{v-u}{t}$
then $s=ut+\frac{at^2}{2}$ again to find distance c

thanks so much!!
