D Question 6 The meterstick in the picture is balanced at the 0.25 m mark. It has a mass of 1 kg. What is the mass of the rock? Hint: think center of mass and torques! 0 kg 1kg 4kg 0.5 kg 0.25 kg
D Question 7 What is the torque due to a 25 N force perpendicular to a 4 m long rod? None of these 6.25 Nm 04 Nm 25 Nm 100 Nm
D Question 8 When you pedala bike when you apply the most torque to the wheel, the figure on the right or the pure on the left, assuming you can exert a maximum of 1000 N worth of force with your weight? The left, because you can put the force at the largest distance from the plot The right, because you can put the force at the least distance from the pivot It doesnt matter, the torque is the same at either The lert, because you can put the force at the smallest distance from the pivot The right, because you can put the force at the largest distance from the pivot Question 9 You hang on the outside edge of the merry go round in the Middletown park yes, they have one!) and pull yourself inward toward the center. Why do you speed up? You inward pull also pushed the wheel around Conservation of momentum Conservation of energy None of these Conservation of angular momentum
D Question 10 You push with a force of 100 N at a distance of 4 m from the pivot of a lever. How much force must you exert at a distance of 2 m away from the lever to exert the same torque? 600N 800N 400N 100N 200N
