Unformatted text preview: ion model are unchanged, so we have
a 1 =  g(sin q  m k cos q ) = 3.20 m / s The kinematics for the return trip are
v 2 = v1 + 2a1 (x 2  x1 ) fi v2 =
2 2 2a 1 x1 = 2 3.20 m /s ( 2 )(7.58 m ) = 6.97 m / s Notice that we used the negative square root because v2 is a velocity with the vector pointing in the xdirection. The final speed is v2 = 6.97 m/s. 2)...
