The formula that describes an objects motion is given by s=ut+1/2at^2, where s is the distance traveled, u is the initial velocity, a is the acceleration, and t is the time. which equation represents a in terms of other variables? a. a=2s-2u/t b. a=2s+2u/t c. 2s-2ut/t^2 d. a=2s+2ut/t^2

We have the following equation:
 s = ut + 1 / 2at ^ 2
 Clear a for the equation:
 1 / 2at ^ 2 = s-ut
 at ^ 2 = 2s-2ut
 a = 2s / t ^ 2-2ut / t ^ 2
 Rewriting:
 a = (2s-2ut) / (t ^ 2)
 
 An equation that represents a in terms of other variables is:
 C. 2s-2ut / t ^ 2

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
