![**Problem Statement:**
At the instant θ = 60°, the boy's center of mass G is momentarily at rest. (Figure 1) The boy has a weight of 70 lb. Neglect his size and the mass of the seat and cords.
**Figure 1:**
The accompanying diagram depicts a boy on a swing, where the cords of the swing make an angle θ with the vertical. At θ = 60°, the swing is positioned at a horizontal distance, where the boy's center of mass (G) is momentarily at rest. The length of the cords is noted as 10 ft.
**Part A:**
Determine his speed when θ = 90°.
Express your answer to three significant figures and include the appropriate units.
*Input Box:*
\[ v = \,\, [ \text{Value} \,\, \text{Units}] \]
**Part B:**
Determine the tension in each of the two supporting cords of the swing when θ = 90°.
Express your answer to three significant figures and include the appropriate units.
*Input Box:*
\[ T = \,\, [ \text{Value} \,\, \text{Units}] \]
