Question

Marbles of mass m are thrown from the edge of a vertical cliff of height h at speed v0. Part A Neglecting air resistance, how fast (in terms of m, h, and v0) will these marbles be moving when they reach the bottom of the cliff if they are thrown straight up? Express your answer in terms of some or all of the variables m, h, v0, and gravitational acceleration g. vfv f = nothing Request Answer Part B Neglecting air resistance, how fast (in terms of m, h, and v0) will these marbles be moving when they reach the bottom of the cliff if they are thrown straight down? Express your answer in terms of some or all of the variables m, h, v0, and gravitational acceleration g. vfv f = nothing Request Answer Part C Neglecting air resistance, how fast (in terms of m, h, and v0) will these marbles be moving when they reach the bottom of the cliff if they are thrown horizontally away from the cliff? Express your answer in terms of some or all of the variables m, h, v0, and gravitational acceleration g.
