Problem 38P

Problem 38P

You are explaining why astronauts feel weightless while orbiting in the space shuttle. Your friends respond that they thought gravity was just a lot weaker up there. Convince them and yourself that it isn’t so by calculating the acceleration of gravity 250 km above the Earth’s surface in terms of g.

Step-by-Step Solution:
Step 1 of 3

Solution 38P Consider in the above problem the wheel spinning in 12 seconds from an initial angular velocity of 0.72 rev/s.the initial angular velocity in rad/s is w i 0.72 rev/s w = (0.72 rev/s)(2 rad/rev) i w i 4.5rad/s The angular acceleration of the wheel is = w/t = ( 4.5 rad/s)/12 sec 2 = 0.38 rad/s Then there is only force acting on the wheel is friction.using above results magnitude of frictional torque is = I = (0.30 kg/m )(0.38 rad/s ) 2 = 0.11 N/m
