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 x-direction. The final speed is |v2| = 6.97 m/s. 2)...
