A stone is thrown vertically upward with a speed of 17.6 m/sm/s from the edge of a cliff 75.0 mm high.
A.)How much later does it reach the bottom of the cliff?
Express your answer to three significant figures and include the appropriate units.
B.)What is its speed just before hitting?
Express your answer to three significant figures and include the appropriate units.
C.)What total distance did it travel?
Express your answer to three significant figures and include the appropriate units.
a. The position of an object is given by x(t) = A + B*t + C*t³ (yes, those exponents are intentional, this is
NOT constant acceleration). Provided that x is measured in meters and t in seconds, what must be the
units for the constants A, B, and C.
b. Another position function is given by y(t) = D # E*t1 + F*t3/2). What are its velocity, and acceleration
functions with time?
c. Bonus: choose and declare your values for D, E and F, and make graphs of y(t), vy(t), and a,(t). Don't
forget appropriate units at each step.
