(350-126)/(5-3)=112m/s
This is the average speed in the time from 3 to 5 seconds...
dd/dt 98,126,154
d2d/dt2 28,28
She actually had a constant acceleration over the entire time period.
The function for that table is:
d(t)=14t^2
Her actual velocity at any point is v(t)=28t (you can see that if you take the mid point of the interval, 4s, you will get the average velocity found earlier)
Answer:
maybe 48
Step-by-step explanation:
it says adam is 12 yrs older so mutiply that by 4
You can do part a using The Pythagoras theorem:-
30^2 = x^2 + 24^2
x^2 = 30^2 - 14^2 = (30+24)(30-24) = 324
x = 18
Answer:
Im not sure, but i think it's the bottom because there not working with negatives
