4.50. Model:We will assume a particle model for the sand, and use the constant-acceleration kinematic equations. Visualize:Solve:Using the equation ()2110010102,xxxxvttatt=+−+−( )1010 mcos150 s0 mxvt°( )160 m/s (cos15 )t=°We can find 1tfrom the y-equation, but note that 00sin15yvv=−°because the sand is launched at an angle below horizontal. 2110102yyyyvtta−( )2101120 m3.0 msin15vt
