A string is wrapped tightly around a fixed frictionless pulley that has a moment of inertia of 0.0352 kg m2 and a radius of 12.5 cm. The string is pulled away from the pulley with a constant force of 5.00 N, causing the pulley to rotate.
What is the speed of the string after it has unwound 1.25 m if the string does not slip on the pulley? A) 2.09 m/s
B) 2.36 m/s
C) 1.18m/s
D) 3.18 m/s
E) 4.95 m/s
