A m = 3.50-kg mass swings as a pendulum on a 38.5 m long string.

(a)

The mass is released from rest when the string is at an angle of 35.0° from the vertical. Find its speed at the bottom of the swing.

m/s

(b)

What would be the speed the mass at the bottom of the swing if it had a speed of 6.00 m/s when the string is at an angle of 35.0° from the vertical.

m/s
