Question

There is a bell at the top of a tower that is 45 m high. The bell weighs 190 Kg. The bell has energy. Calculate it.

Answer 1

Answer:

$\boxed{\orange{\sf Potential \ Energy = 8.7 \times 10^4\ J .}}$

Explanation:

Given that a ball of mass 190kg is placed at a tower of height 45m . We need to calculate the energy. Since the ball is located at a height and is at rest , therefore , it will possess Potential Energy .

• Potential Energy of a object of mass m placed at a h height is given by mgh , where g is the acceleration due to gravity .

$\sf\dashrightarrow Energy = mgh \\\\\sf\dashrightarrow Energy = (195kg)(10m/s^2)(45m) \\\\\sf\dashrightarrow\boxed{\pink{ \sf Energy_{(potential)}= 87750 \ Joules }}$

Answer 2

Answer:

❇ Given :

➡Given that a ball of mass 190kg is placed at a tower of height 45m .

➡We need to calculate the energy.

Since the ball is located at a height and is at rest , therefore , it will possess Potential Energy .

❇ Solution :

➡Potential Energy of a object of mass m placed at a h height is given by mgh , where g is the acceleration due to gravity .

⭐ Energy = mgh

➡ Energy = (195kg) (10m/s² ) (45m)

➡ Energy (potential) = 87750 Joules

❇ Answer : 87750 J
