What was the runners centripetal acceleration, a, in m/s, during the run?
The "classical" radius of a neutron is about 0.81 fm (1 femtometer = 10-15 m). The mass of a neutron is 1.675×10-27 kg.
a) Assuming the neutron is spherical, calculate its density in kilograms per cubic meter.
b) What would be the magnitude of the acceleration due to gravity, in meters per second squared, at the surface of a sphere of radius R = 1.2 m with this same density? Recall that the gravitational constant is G = 6.67 × 10-11 m3/kg/s2.
