4.50. Model: We will assume a particle model for the sand, and use the constant-acceleration kinematic equations. Visualize: Solve: Using the equation () 2 1 100 1 0 1 0 2 , xx x xvtt a tt =+ −+ ( ) 10 1 0 m cos15 0 s 0 m xvt ° ( ) 1 60 m/s (cos15 ) t = ° We can find 1 t from the y -equation, but note that 00 sin15 y vv = −° because the sand is launched at an angle below horizontal. 2 1 1 0 1 0 2 yy yyvtt a ( ) 2 1 01 1 2 0 m 3.0 m sin15 vt
