For Question 2 realize that you need to account for the effect of the person: either they are falling with the plank (so theyapply their weight to the plank and add to its rotational inertia) or they are not (so their force on their board is not equalto their weight but they do not increase the rotational inertia). You may solve this either way--they both give the sameanswer.Question 11 ptsA heavy, 6 m long uniform plank has a mass of 30 kg. It is positioned so that 4 m is supported on thedeck of a ship and 2 m sticks out over the water. It is held in place only by its own weight. You have amass of 70 kg and walk the plank past the edge of the ship. How far past the edge do you get beforethe plank starts to tip, in m?Question 2If you go 10 cm past the point determined above, what is the angular acceleration of the board inrad/s²?1 pts

The moment of inertia of an object about a certain axis is 1.2 kg-m2. Initially the object is at rest, and then it is accelerated at a constant rate of 25 rad-s-2. Determine the time required for the object to achieve a rotational kinetic energy of 1.50 kJ.
1. An Olympic athlete competing in the hammer toss spins the 7.26 kg hammer in a circle having a radius of 2.15 m (this includes both the length of the massless cable attached to the hammer and the athlete's arms). If the angular speed of the hammer is 13.4 rad/s about the axis of rotation just before the athlete releases the hammer, what is the tension force in the cable attached to the hammer at this moment? Treat the hammer like it is a point mass at the end of a massless cable. 2. Your car has a mass of 1.30 x 103 kg. You get on Crondall Lane and are cruising along at 20.0 m/s and thinking about how you really should have walked across the bridge instead of contributing to global pollution. You look up to see that you are approaching the stoplight at Owings Mills Boulevard and it is red, so you slam on the brakes when you are 25.0 m away from the light. If your brakes provide a constant force of 8.90 x 103 N, do you stop before reaching the stoplight? If not, how fast are you…
