1.	4500 J of energy is used to raise an object with a mass of 50 kg to a height h .Calculate h
Answer» Given :- Potential ENERGY (P.E) = 4500 J Acceleration de to gravity (g) = 10 (APPROX of 9.8) MASS (m) = 50 kg. To Find :- Height (H) We have to find the height (h) here and we know the formula of Potential Energy (P.E) = m × g × h In this, we have P.E , m & g and h isn't there So, we PUT the values and solve it → P.E = m × g × h → 4500 = 50 × 10 × h → 4500 = 500 h → 500h = 4500 → h = 4500/500 → h = 9 Thus, the height is 9 m

Answer»

Given :-

Potential ENERGY (P.E) = 4500 J
Acceleration de to gravity (g) = 10 (APPROX of 9.8)
MASS (m) = 50 kg.

To Find :-

Height (H)

We have to find the height (h) here and we know the formula of Potential Energy (P.E) = m × g × h

In this, we have P.E , m & g and h isn't there

So, we PUT the values and solve it

→ P.E = m × g × h

→ 4500 = 50 × 10 × h

→ 4500 = 500 h

→ 500h = 4500

→ h = 4500/500

→ h = 9

Thus, the height is 9 m
