Answer:
There are no answer chooses to this question
Explanation:
Initial velocity = 
acceleration in the downward direction = -9.8 
Final velocity at the highest point = 0
Maximum height reached = 0.410 m
Now, Using third equation of motion:




Speed with which the flea jumps = 
1 Watt = 1 joule/second
650 watts = 650 joules/second
(650 J/sec) x (3,600 seconds/1 hour) = <em>2,340,000 Joules/hour</em>
Answer:
100 watt
Watt is a unit of power, for the light bulb its produces or consumes 100 watts of power
The unseen force of gravity acts on the sled,
accelerating it downward.
