The correct answer would be D. A new experiment would be needed to be done in order to test the conclusions. In science there is no authority, data is the only thing that matters. So if we have two different conclusions from the same date the only solution is to perform more tests and more experiments to see what is correct.
Answer: 16N
Explanation:
Given that:
mass of box M= 2 kg
Initial speed V1 = 4 m/s
Final speed V2 = 8 m/s
Time taken T= 0.5 s
Average strength of this force F = ?
Now, recall that Force is the rate of change of momentum per unit time
i.e Force = momentum / time
Hence, F = M x (V2 - V1)/T
F = 2kg x (8 m/s - 4 m/s) / 0.5s
F = 2kg x (4 m/s / 0.5s)
F = 2kg x 8 m/s/s)
F = 16N
Thus, the average strength of this
force is 16 newton.
The tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.
<h3>
Tension in the cable</h3>
The tension in the cable supporting the swing of the ball is calculated as follows;
T = mg + mac
T = mg + m(v²)/r
T = (4810 x 9.8) + (4810 x 1.06²)/12.3
T = 47,577.4 N
Thus, the tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.
