Question

These have been the answers previously given by Cramsterexperts but this is the wrong answer. I have tried over and over with other equations but they havebeen wrong. Please help with this one. let the init speed of the block be v0 , for energyconservation, we have: (1/2)mv02 =(1/2)k(x)2 here m=0.150kg, x=4.50cm=0.0450m, k= 54.0 N/m =>v0 =[(k/m)]x=[(54.0N/m/0.150kg)]*0.0450m =0.85m/s let the init speed of the block be v0 , for energyconservation, we have: (1/2)mv02 =(1/2)k(x)2 here m=0.150kg, x=4.50cm=0.0450m, k= 54.0 N/m =>v0 =[(k/m)]x=[(54.0N/m/0.150kg)]*0.0450m =0.85m/s let the init speed of the block be v0 , for energyconservation, we have: (1/2)mv02 =(1/2)k(x)2 here m=0.150kg, x=4.50cm=0.0450m, k= 54.0 N/m =>v0 =[(k/m)]x=[(54.0N/m/0.150kg)]*0.0450m =0.85m/s here m=0.150kg, x=4.50cm=0.0450m, k= 54.0 N/m =>v0 =[(k/m)]x=[(54.0N/m/0.150kg)]*0.0450m =0.85m/s

Mass (m) = 0.150 kg ; Final velocity (v2) = 0 ( as it is comingto rest )

. From the conservation of Energy :

  m (vo )2    =   k x2   

(vo )2  =  (   k x2  ) /m  

vo= sqrt [( k x2) / m]= sqrt [( 54.0 * (4.50 * 10-2) /.150]  = 0.854 m /s

Explanation / Answer

here m=0.150kg, x=4.50cm=0.0450m, k= 54.0 N/m =>v0 = [k(x)2/m +2g(x)] = [(54.0N/m/0.150kg)]*0.0450m = 1.27 m/s
