Question

How much is the mass of a man if he has to do 2500 joules of work in climbing a tree​

Answer 1

Answer:

Explanation:

Hence, The mass of the man if he has to do climbing work on a tree 5m tall is 50kg

Answer 2

Answer:

50 kg

Explanation:

Given

Mass of the man = ?

Potential Energy = 2500J

Height = 5m

g = 10 ms - ¹

Solution

We know that the formula to find Potential energy is

Ep = mgh

No we apply the given values in this equation.

2500J = m × 10 × 5

2500J = 50m

{\frac{2500}{50}}

50

2500

Hence, The mass of the man if he has to do climbing work on a tree 5m tall is 50kg.
