Question

How high must a sack of sugar weighing 10 kg be lifted to have 58 J of potential energy? (Hint: Derive the formula of PE-mgh to get the formula for height. Divide both sides by the variable/s adjacent to height (h) to get h=PE/mg)

Answer 1

Answer:

Answer:

A = 1.03

Explanation:

G - PE = 101J

m = 10kg

g = 9.8m/s^2

E - h=PE / (m) (g)

S - 101J / (10kg) (9.8m/s^2)

A - 101 / 98

= 1.03
