x(2) = 30(2) = 60 m
y(2) = ½(-9.8)2² = -19.6 m
x(4) = 30(4) = 120 m
y(4) = ½(-9.8)4² = -78.4 m
x(6) = 30(6) = 180 m
y(6) = ½(-9.8)6² = -176.4 m
x(8) = 30(8) = 240 m
y(8) = ½(-9.8)8² = -313.6 m
x(10) = 30(10) = 300 m
y(10) = ½(-9.8)10² = -490 m
Answer:
Explanation:
The potential energy associated with a body (m) located at a given height (h) above a reference point is defined as:
At the reference point the potential energy is zero. In this case the body is below the reference point (the ceiling), therefore, the value of h is negative:
