Answer:
23.9m
Explanation:
step one:
This problem is on energy.
we can proceed by using the expression for potential energy to solve for height h
we know that
PE=mgh
given that
mass m= 5kg
PE= 1176 joules
step two:
we can substitute our data and find h
1176= 5*9.81*h
1176=49.05h
step three:
divide both sides by 49.05 we have
1176/49.05=h
h=23.9 m
The height of the tree is 23.9m
