U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
Answer:
4,337 goes on top & 8 on the bottom
----------
8 & the answer is 542.12
Answer:
13:11
Step-by-step explanation:
325:275
If divided by 5 all through, you get 65:55, then by 5 again you get 13:11
Answer:
Step-by-step explanation:
Remark
You need the work done (I think), and the power developed from the givens. This question is just a straight forward application of the formulas for work and power.
Givens
F = 100 N
d = 5 meters
t = 15 seconds
Formulas
W = F * d
Power = F * d / t
Solution
<u><em>Work</em></u>
W = 100 N * 5 meters
W = 500 Newton Meters or 500 J
Work = 500 Joules
<u><em>Power</em></u>
P = F * d / t
Power = 100 * 5 / 15
Power = 33.3 Watts.
