Question

An object with 100 N weights is raised to a height of 15m. Find the potential energy possessed by the object at that height. Also find the new potential energy:
a.)If the same object is raised half of its original height.
b.)If the same object is raised to three times of its original height?
Given g=10m/s2​

Answer 1

Answer:

the answer is

(a) 750J

(b) 4500J

Explanation:

It is given that,

Weight of the object, W = 100 N

Height at which the object is reached, h = 15 m

We need to find the potential energy. It is said to be possessed by an object by virtue of its position or height above ground. It is given by :

P = 1500 Joules

(a) If same object is raised half of its original height, h' = h/2 = 7.5 m

Potential energy is given by :

P = 750 Joules

(b) Object raised to three times of original height, h' = 15(3) m = 45 m

P = 4500 Joules

Hence, this is the required solution.
