Question

Hello,I wanna asked if my answer is correct...

 

For A to B I am using Ta+Va=Tb+Vb

And I get 

Ta= 0 since there is no velocity

Tb = ½(50)(VB)²=25(VB)²

Va=½ks² = ½(2000)(0.6)² =600N

Vb=mgh =(50)(9.81)(0.9)= 441.45

 

Then  Vb =2.52 m/s

And then using vertical motion from b to c to find t

Y=Y initial+(V sin36.87)tBC+1/2a(tBC)²

Then t = 0.609s

 

And find d using d=(vcos36.87)t

d=1.23m

 

Is my answer and method correct? Sorry for my bad english
