A 30 kg block m is placed on a 20 cm compressed spring which held by a stopper as shown in Figare 1.2. A conveyor moving with a velocity of 5 m/s awaits at the top of the incline. Once the stopper is released, the spring uncompresses and pushes the block, causing it to travel up the incline toward the conveyor. To prevent jerking, the block needs to arrive at the top with the same velocity. If the coefficient of kinetic friction between the block and the surface is M = 0.1, determine the spring constant k needed to achieve this using principle of work and energy method for the particle. stopper 30 conveyor 000 (17 marks) Figure 1.2 Block motion up to incline toward the conveyor A 30 kg block m is placed on a 20 cm compressed spring which held by a stopper as shown in Figure 1.2.
