In her physics lab, Jessica rolls a 20-g marble down a ramp and off the table with a horizontal velocity of 1.10 m/s. The marble falls in a cup placed 0.44 m from the table's edge. Find the table's height. Use g = 10. m/s2. Enter m as unit.

  • Physics -

    X = V*t = 0.44 m.=Hor. dist from table.
    1.1*t = 0.44
    Tf = 0.4 s. = Fall time or time in air.

    h = Vo*t + 0.5g*t^2.
    h = 0 + 5*0.4^2 = 0.8 m.
