Using a forked rod, a smooth cylinder P, having a mass of 0.4 kg, is forced to move along the vertical slotted path r- (0.60) m, where e is in radians. If the cylinder has a constant speed of te- 2 m/s, determine the force of the rod and the normal force of the slot on the cylinder at the instant e- rad. Assume the cylinder is in contact with only one edge of the rod and slot at any instant. Hint To obtain the time derivatives necessary to compute the cylinder's acceleration components a, and a, take the first and second time derivatives of r- 0.60. Then, for further information, use Eq. 12-26 to determine 8. Also, take the time derivative of Eq. 12-26, noting that te - 0, to determine 8. -060

A cart has a mass of 1.5 kg. It is given some initial push toward a sensor and is slowed by a hanging mass which makes the cart turn around and speed up as it returns to its original position. This situation is illustrated in the attached image. If the acceleration towards the sensor is 0.5 m/s2 and the accaleration away from the sensor is 0.15 m/s2, a. draw the free body diagrams for the cart moving towards the sensor and away from the sensor. b. Write Newton's law for both situations and solve for the frictional force and for the force from the hanging mass.
