With a mass of 2.0 kg, the ball B (vB1) = 2.4m/s and rotates in an orbit with a radius of r1 = 0.8 m. From this moment on, the rope attached to it is 1.2m / s. Find the velocity of ball B at the moment r2 = 0.5 m since it is pulled with its velocity Vr = as shown in the figure. Also calculate the work required to pull the rope.

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.
