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 m, h, and v0.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 m, h, and v0.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 m, h, and v0.Part D) Will the final velocity vectors of the marbles be the same or different for each case?a. The final velocity vector is the same for parts (b) and (c) but differs for part (a).b. The final velocity vector is different for all of the parts. c. The final velocity vector is the same for parts (a) and (c) but differs for part (b).d. The final velocity vector is the same for all of the parts. e. The final velocity vector is the same for parts (a) and (b) but differs for part (c).
