1. 2500/60 joules/sec
2. 2,500Nm
D.6.22N. because .42kg * 14.8m/s=6.22 N[meaning newtons}.
Answer:
The first one (60%)
Explanation:
The first one converts 15% more energy than the other one. Therefore, it is more efficient.

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.
