exercise can lower levels
The answer for Apex is D.
Mass of Derrick at a height 4.3 m having 2730 joule of energy is 65 Kg.
<h3>What is the expression of gravitational potential energy near the earth surface?</h3>
- Mathematically, gravitational potential energy near the earth surface= m×g×h
- m= mass of Derrick, g= acceleration due to gravity, h= height at which Derrick present
- Then, mass (m) of Derrick = potential energy/ (g×h)
<h3>What is the mass of Derrick, if he gains 2730 joule of energy at 4.3m above the ground?</h3>
Mass of Derrick= 2730/(9.8×4.3)
= 65 kg
Thus, we can conclude that the mass of Derrick is 65 Kg.
