and the angle El = 39". The wire can withstand a maximum tensipn at 450 N. We place the hlccls: at distance x that creates that
maximum tensicn in the wire. What is the value at: x? I; t 1.3. on. hum

block is given by x = {1.50 cm) cos{o.rt + #2}. Block 1 of mass 5.40 kg slides toward block 2 with a velocity of magnitude 4.00 mfs, directed along the spring's length. The two hloclcs undergo a completelyr inelastic collision at time t= 4.00 ms. {The duration of the collision is much less than the period of motion.)
