Lab
In this lab you will be given some values for a vector and will need to determine the missing values. Then, you will test your answers using one of the force tables. All angles need to be in the range from 0° to 360°, where 0° points along the positive x-axis,
90° points along the positive y-axis, 180° points along the negative x-axis, and 270° points along the negative y-axis. For the vector -A, the negative of a vector is antiparallel to the vector itself.

Problem 1: A book is resting on a frictionless table until someone suddenly starts applying a constant
force on it right until it reaches the end of the table. The book was constantly accelerating until it reached
the end of the table.
First, write down your thinking process as in the previous example, and then draw in the space provided
below the book's motion diagram along with the velocity, acceleration, and force vectors.
Draw book's motion diagram with velocity, acceleration, and force vectors. (Hint: Since the motion
is horizontal, draw a horizontal motion diagram.)
Use the information below to answer parts a–f. Show all your work including vectordiagrams, formulas, etc.
A soccer ball is kicked at an angle of 32.0 ̊ above the horizontalwith an initial velocity of 25.0 m/s.
a) Determine the horizontal component of the initial velocity.
b) Determine the vertical component of the initial velocity.
c) What is the ball’s horizontal velocity at 2.00 s?
d) What is the ball’s vertical velocity at 2.00 s?
e) What is the horizontal displacement at 2.00 s?
f) What is the vertical displacement at 2.00 s?
