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)
Answer:
An equation that represents a in terms of other variables is:
C. 2s-2ut / t ^ 2
Answer: 37
Step-by-step explanation:
The answer is 735 J
<span>A work (W) is a product of a force (F) and a
distance (d):
W = F · d
</span>
W = ?
F = 245N
d = 3m
W = 245N * 3m
W = 735 J
