What factor or quantity is primarily responsible for the constant change in velocity for the vertical velocity component of the projectile while in free-fall? How would you describe this quantity? In other words, is it a constant value, or is it, too, always changing?
Homework Answers
It is gravitational force which is primarily responsible for the constant change in velocity for the vertical velocity component of the projectile while in free-fall? It does not change with time but do changes with distance of projectile from the centre of earth.

PROBLEM 4: In your physics class, projectile motion has two components: constant-velocity motion in the horizontal direction and free-fall motion in the vertical direction. However, in reality, the horizontal motion has acceleration due to air resistance, wind, and other factors. The goal of this problem is to visualize the trajectory of a projectile...

Imagine a 4.0-kg wood block sliding across a horizontal table surface with a positive velocity and an acceleration of -2.0 m/s. You need to calculate the coefficient of kinetic friction for these two surfaces. 1. Start the same way you always should whenever you have a question involving forces and accelerations. Draw a free-body diagram (arrows for all the forces, arrow for net force, and a coordinate system) for the block. All the forces, vertical as well as horizontal. 2....

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...
