how can i get height in a free fall problem. what's the formula

ohhh ok thank you so much for your help!

I know the vo is 20.0 and the time is 40.0 but i am not sure about the vf is it 0??

I know the formula, I am just confuse understanding the problem, I know in the first interval the vf is 20.0 an the vi is 0 the t is 10.o so a=2.0, but in the second interval i am confused about the values that i am supposed tu use.

Can somebody explain to me how to get the acceleration in the second and third interval please. A car starts from rest and accelerates uniformly for 10.0s, reaching a speed of 20.0m/s. It then continues traveling at that speed for 40.0 additional seconds before decelerating uniformly and...

thank you so much for your help

but the displacement's formula is final value-initial value, an the rf=1200m ant the initial=500

so the total displacement is going to be 700m

i was trying to get the displacement using the formula, so the total displacemt must be 1700m, is that right?

Please can somebody help me with this problem.A car undergoes a displacement of 500m due east, followed by another displacement due south of 1200m. a) Calculate the total distance traversed by the car. b) Calculate the total displacement of the car.
