2. The 2-kg package leaves the conveyor belt at A with a speed of VA = 1 m/s and slides down the smooth ramp. Determine the required speed of the conveyor belt at B so that the package can be delivered without slipping on the belt. Also, find the normal reaction the curved portion of the ramp exerts on the package at B if PB = 2 m. V₁ = 1 m/s 4 m UB X
