Answer 1

I'm stuck, I don't even know where to start

Answer 2

use conservation of energy.

Answer 3

So help me solve it?

Answer 4

first find the height as h = 30 - 30 cos (37) = 6m

Answer 5

so is that the start?

Answer 6

then\[\frac{ 1 }{ 2 }mv^{2} = mgh\]\[v^{2}=2gh\]\[v^{2}=2\times9.8\times6\]

Answer 7

ok then what

Answer 8

find v

Answer 9

so its 10.84 correct?

Answer 10

whats it measured in?

Answer 11

m/s
