Problem 42PE

Calculate the displacement and velocity at times of (a) 0.500, (b) 1.00, (c) 1.50, (d) 2.00, and (e) 2.50 s for a rock thrown straight down with an initial velocity of 14.0 m/s from the Verrazano Narrows Bridge in New York City. The roadway of this bridge is 70.0 m above the water.

Solution 42PE

Step 1 of 12

A rock is thrown straight downwards from with initial velocity as shown in the figure below. Here we need to calculate the displacement and velocity at different times.

Using the given data, we need to calculate the displacement and velocity using kinematic equation at different times ,,, and .
