0%) Problem 2: A ball is thrown vertically with velocity vi from a height of h 26 m d lands on the ground after a time interval Δ. The positive y-direction is upward. Refer the figure. Otheexpertta.com ψ 13% Part (a) what is the value of the vertical component of acceleration of the free fall motion in meters per second squared? -9.8 =-9.8 V Correct! 13% Part (b) Enter an expression for the vertical component of the total displacement of the motion. Ay, in terms of initial height h. 13% Part (c) Enter an expression for y in terms of Δ, a, and the vertical component ofthe initial velocity of the motion, vi. 13% Part (d) If the ball starts from rest, what is vi.in meters per second? -0 Correct 13% Part (e) Enter an expression for Δ, in terms of a and Ay, in the case when the ball starts from rest. ее 13% Part (f) Calculate the fall time a, in seconds, when the ball starts from rest. -2.30 r-2.3 Correct 13% Part (g) Returning now to the general case, wi # Il hits the ground, in terms of vi, a, and Ar ,-v\" a Δ' V Correct! , enter an expression for the vertical component of the final velocity, v , right before the ag 13% Part (h) Calculate the value of Vf in meters per second when the ball starts from rest.
