Need help with 35 PLZ urgent

Mathematics
1 answer:
Sophie [7]3 years ago
3 0

The formula is K = v^2 /2

You are told K = 32.

Replace K and solve for v:

32 = v^2 / 2

Multiply each side by 2:

64 = v^2

Take the square root of both sides:

v = √64

v = 8 meters per second.

18 hours.

Proportions and stuff.

\frac{204}{4} = \frac{918}{x}
