Question

A gargoyle statue falls off the side of a building from a height of 75 m. (Assume, no air resistance.) a. How fast is the statue moving after 1.75 seconds? (1 point). B: How long does it take the statue to reach the ground? (1 point)

Answer 1

how fast is the statue moving ---> vf^2 = vi^2 + 2ad, where vf is the final velocity, vi is the intiial velocity (if it simply fell off, without being pushed, initial velocity = 0), a is the acceleration due to gravity (9.81 m/s/s), and d is the distance (75m). plug in and solve for vf.

How long does it take the statue to reach the ground? ---> vf = vi + at, plug in vf from the previous step, vi is still 0, a is still 9.81, solve for t
