Another physics question
I think this may be correct I just need a second set of eyes on it to look it over. Thanks in advance.
The question is:
A small block of mass m1 =0.500kg is released from rest at the top of a curve shaped frictionless wedge of mass m2=3.00kg, which sits on a frictionless horizontal surface. When the block leaves the wedge, its velocity is measured to be 4.00 m/s to the right
a) what is the velocity of the wedge after the block reaches the horizontal surface
b) what is the height h of the wedge
Vwedge=(-mBlockVblock)/mWedge = -(0.500)*(4)/3
Vwedge= 0.667 m/s
(0+Mblock*g*h=1/2*Mblock*V^2block + 1/2*Mwedge*v^2wedge+0)
h= (1/2*Mblock*V^2block + 1/2*Mwedge*v^2wedge)/gMblock

Looks OK to me. Better use 2/3 than .668

naa, this is a physics class, not a Calculus class. Exact numbers rounded to 3 places is best.
Thanks for the check.
Peace out bro
