Problem 36E

A small rock is thrown vertically upward with a speed of 18.0 m/s from the edge of the roof of a 30.0-m-tall building. The rock doesn’t hit the building on its way back down and lands in the street below. Air resistance can be neglected. (a) What is the speed of the rock just before it hits the street? (b) How much time elapses from when the rock is thrown until it hits the street?

Step-by-Step Solution:

Solution to 36E A rock is thrown upwards with an initial velocity of 18m/s. After some time it will hit the ground. To find the time taken to reach the ground and velocity of the rock when it reaches the ground, following steps should be followed. Step 1 s=16.53m This is the height to which the rock reaches when it is thrown upwards. The total distance the rock travels back to the ground is, Distance the rock travels upwards+Height of the building=30+16.53=40.53m Thus s’=40.53m Step 2 To find the velocity of the rock when it reaches the ground, v=30.166m
