Power = (work done) / (time to do the work)
Power = (2000 J) / (5 sec)
<em>Power = 400 watts</em>
Ick! Word problems! They suck. Okay so first of all you want to narrow it dow the equation.
Step 1. What are the numbers? (In this case 12 m/s and 25 m/s)
Step 2. Are you multiplying, dividing? (In this case your dividing)
Step 3. Divide.
I hope that helps.
Answer:
g = 12.22 m/s²
Explanation:
The time period of this pendulum is given as follows:

but the formula for the time period of a simple pendulum is as follows:

where,
L = length of pednulum = 48 cm = 0.48 m
g = magnitude of th gravitational acceleration on this planet = ?
Therefore,

<u>g = 12.22 m/s²</u>
