Ok this is another problem I am having trouble with.
In a 100 m race, Maggie and Judy cross the finish line in a dead heat, both taking 10.2 s. Accelerating uniformly, Maggie took 2.10 s and Judy 3.10 s to attain maximum speed, which they maintained for the rest of the race. What was Maggie's acceleration?
Ok so I know that
Si (initial distance)= 0 m
Sf (final distance)= 100m
Delta T = 10.2s (10-0)
Vi( Initial velocity of maggy and Judy) = 0 m/s
I think Judy's time is there just to distract us, because every time I try to use both set of data and plug them into a kinematic equations for motion with constant acceleration, I reach a dead end.
So I tried a different method
100m - Sf = 1/2 * a * (2.10s) ^ 2
100m - Sf = 2.205A
A = (100m-Sf)/2.205
And Then I tried to plug that back into the SF equatoin but that didn't help.
Can anyone point me to the right direction?
