1. A soccer player with an initial velocity of 0 (rest position) accelerates uniformly as she runs down the field travelling 17m [E] in 3.8s. What is her final velocity?
2. A skier sits at rest on top of a hill. If the skier travels 70m [down] in 5.3s while accelerating uniformly, what acceleration does he experience?
a = (vf-vi)/t ?
The Attempt at a Solution
So I used the above equation to try and solve these but they're not working?
The answer to 1 is supposed to be 8.9m/s[E] and the answer to 2 is 5.0m/s2 [down].
