A personal letter written to a friend using 1st person
Answer:
B) Power
Explanation:
The power is defined by the following equation:
P = W / t
where:
W = work = Force * Distance = [Newton] * [meter]
t = time = seconds
The units for work are give en Newton per second, which is equal to Joules
And for power the unit used commonly is Watts, therefore:
Watts = (Joule/second)
a=(5.8-1.5)÷15.8
a=4.3÷15.8
a=0.27m/s
Explanation:
acceleration=final velocity - initial velocity /time
