The ball is released from position A with a velocity of 3 m/s and swings in a vertical plane. At the bot- tom position, the cord strikes the fixed bar at B, and the ball continues to swing in the dashed arc. Calculate the velocity vc of the ball as it passes position C. Ans. ve = 3.59 m/s

Thank you in advance

Current Attempt in Progress The speed of a car increases uniformly with time from 63 km/h at A to 103 km/h at B during 8 seconds. The radius of curvature of the hump at A is 60 m. If the magnitude of the total acceleration of the mass center of the car is the same at B as at A, compute the radius of curvature pg of the dip in the road at B. The mass center of the car is 0.74 m from the road. Assume PA = 60 m, h = 0.74 m. Answer:PB = m B PB

2/42 Packages enter the 3-m chute at A with a speed of 1.2 m/s and have a 0.3g acceleration from A to B. If the packages come to rest at C, calculate the constant acceleration a of the packages from B to C. Also find the time required for the packages to go from A to C. A -3 m B Problem 2/42 3.6 m C

2. Determine the kinetic energy of the 60-lb block A at this instant if the 40-ib block B is traveling uphill with a speed of 1.5 ft/s. Also calculate the kinetic energy of block B. 60° 30

Tractor A used to hoist bale B with pulley shown, if tractor have constant foward velocity Va= 15 ft/s, find upward velocity Vb at instant when x =30 ft.
