Adian for one of the answers i think its 2Cr + 3Cl2 --> 2CrCl3 correct me if im wrong. None of these were on my quiz so im going to try to figure out the other two
The height of the ball is 2.45 m.
To calculate the height of the ball, we use the formula below.
<h3>Formula</h3>
- E = mgh................ Equation 1
Where:
- E = Elastic energy of the spring
- m = mass of the ball
- h = height of the ball
- g = acceleration due to gravity.
make h the subject of the equation
- h = E/mg...............Equation 2
From the question,
Given:
- E = 7.2 J
- m = 0.3 kg
- g = 9.8 m/s²
Substitute these values into equation 2
- h = 7.2/(0.3×9.8)
- h = 7.2/2.94
- h = 2.45 m
Hence, The height of the ball is 2.45 m.
