x - t, y - t, v_x - t and v_y - t graphs for the motion. (Do this on paper. Your instructor may ask you to turn in this work.) swimmer dives off a cliff with a running horizontal leap, as shown in the figure below. What must her minimum speed be just as she leaves the the ledge at the bottom, which is w = 1.25 m wide and h = 6.00 m below the top of the cliff? Chirpy and Milada, jump from the top of a vertical cliff. Chirpy just drops and reaches the ground in 3.29 s, while Milada jumps horizontally with a far from the base of the cliff will Milada hit the ground?

Explanation / Answer

consider the motion along the vertical direction :

Voy = initial velocity = 0 m/s

Y = vertical displacement = h = - 6 m

a = acceleration = - 9.8

t = time = ?

using the equation

Y = Voy t + (0.5) a t2

- 6 = 0 t + (0.5) (-9.8) t2

t = 1.11 sec

consider the motion along the X-direction

Vox = initial velocity = Vo

X = displacement = w = 1.25 m

using the equation

X = Vox t

1.25 = Vo (1.11)

Vo = 1.13 m/s
