Problem 21CQ

object that is thrown straight up falls back to Earth. This is one- dimensional motion. (a) When is its velocity zero? (b) Does its velocity change direction? (c) Does the acceleration due to gravity have the same sign on the way up as on the way down?

Step-by-Step Solution:

Step-by-step solution Step 1 of 3 (a) When an object is thrown straight up, its velocity decreases continuously. Once it attains the peak height, the velocity reduced to zero and then the object starts falling. So, the velocity is zero at the highest point.
