<u>Given that:</u>
height (h) = ?
mass (m) = 2 Kg ,
Potential energy (P.E.) = 100 J ;
We know that P.E = m × g × h
100 J = 2 × 9.81 × h
h = (100) ÷ (2 × 9.81)
<em> h = 5.09 m</em>
Answer:
13.2m
Explanation:
Step one:
given data
Energy= 5610J
Force F= 425N
Required
The distance traveled
Step two:
We know that work done is given as
WD= force* distance
so
5610=425*d
divide both sides by 425
d= 5610/425
d=13.2m
