(a) A thin rod of length h and mass M a) A thin rod of length h and mass M is held vertically with its lower end resting on a frictionless horizontal surface. The rod is then released to fall freely. Determine the speed of its center of mass just before it hits the horizontal […]

A bicyclist traveling with speed v = 4.2 m/s on A bicyclist traveling with speed v = 4.2 m/s on a flat road is making a turn with a radius r = 6.4 m. The forces acting on the cyclist and cycle are the normal force (Fn) and friction force (Ffr) exerted by the road […]

Matlab program help! My directions were to modify the following matlab code to incorporate a new input variable called ‘nstep’ and change the programs operation to store and print the output only a few each nstep iterations instead of every time. I’m a little confused as to what this means. Any help would be much […]

(a) What is the rotational kinetic energy (a) What is the rotational kinetic energy of the Earth about its spin axis? Model the Earth as a uniform sphere and use data from the endpapers. (b) The rotational kinetic energy of the Earth is decreasing steadily because of tidal friction. Find the change in one day, […]

Rigid rods of negligible mass lying along the y axis connect three particles (Fig. P10.20). If the… Rigid rods of negligible mass lying along the y axis connect three particles (Fig. P10.20). If the system rotates about the x axis with an angular speed of 2.00 rad/s, find (a) the moment of inertia about the […]

a) Determine the acceleration of the center a) Determine the acceleration of the center of mass of a uniform solid disk rolling down an incline making angle ? with the horizontal. Compare this acceleration with that of a uniform hoop. (b) What is the minimum coefficient of friction required to maintain pure rolling motion for […]
