- The ball has a mass of 1 kg and is confined to move along the smooth vertical slot due to the rotation of the smooth arm OA. The rod is rotating with a constant angular velocityd slot at any instant. Which one of the following is (are ) incorrect answers ? =2 rad/s. Assume the ball contacts only one side of the ion e-2 rads Select one or more: There is only one contact force on the ball that is acting perpendicular to the rod. There are two contact forces on the ball: one is acting perpendicular to the wall, and the other is perpendicular to the rod. The path of the ball is given by r 0.5 sec 0. The acceleration along the 0 increasing direction is a, tan 6 sec 00 The normal reaction to the ball by the rod is given by the equation N gcos+ a, whiere ap s the acceleration along the 6 increasing direction.This question is similar to one given to me on my homework assignment. I do not understand the values given for the radius (given by my instructor) when trying to find the angular velocity of point E. What radius values and or diameter values do I have to use regarding pythagoreans theroem to obtain the needed radius to plug into VE=rwBeam 1 with block 2 hanging from it is supported as shown. The mass of block 2 is m2=150 kg, theta=55∘, and x=7 m. You choose the lower left end of the beam as the axis of rotation, and you call clockwise the positive torque direction. Calculate the torque due to the weight of block 2 on the block+beam system.
- A ball of mass 5.5 kg is released from rest from the top of a 4.0 m long hill that is inclined at 30°, as shown in figure. The ball rolls along the hill without slipping. The rotational inertia of a sphere of mass M and radius R about its center of mass is MR. (cos 30° = 0.866, sin 30° = 0.5, g = 9.8m/s?) a) Calculate the force due to friction acting on the ball as it rolls along the hill, b) Calculate the linear speed of the center of mass of the ball when it reaches the bottom edge of the hill, c) A wagon containing a box is at rest on the ground below the hill so that the ball falls the vertical distance of 3.0 m and lands and sticks in the center of the box. The total mass of the wagon and the box is 12 kg. Calculate the horizontal speed of the wagon immediately after the ball lands in it. 4,0 m 3.0 mConsider the image below of a hammer throw. At the point of release of the hammer, an athlete has an angular velocity of 2.70 rad/sec.
