- Determine the magnitude of force P to move block BA 8.0 kg mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown in (Figure 1). What does the spring scale read just before the mass touches the lower spring? The scale reads 16 NN when the lower spring has been compressed by 1.7 cmcm. What is the value of the spring constant for the lower spring? At what compression length will the scale read zero?An ideal spring can compress 2.33 cm by a force of 555 N, a block of mass m = 3.18 kg is released from rest on an inclined plane, the onclination of the plane is 32 degrees, the block rest momentarly when the spring is compress 5.48 cm. Find the distance d that the block travels from the begining of the motion until it reaches the spring. (g = 10 m/s2 ).
