Answer:
a) 4 -
b) 1 -
c) 6 -
Step-by-step explanation:
It simply asks the steps to go from the original displacement formula to isolate a (the acceleration). It's just a matter of moving items around.
We start with:
We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):
Then we multiply each side by 2 to get rid of the 1/2, answer #1:
Finally, we divide each side by t^2 to isolate a (answer #6):
