- Express the
**vector**in polar form. Possible Answers: Correct answer: Explanation: We know that converting into polar form requires using the formulas : and . Solving for r will give us the equation: We can then solve this equation for theta thusly: We substitute the values of x and y found in the**vector**equation to get the angle measure: - Add/subtract any constant to the opposite side of the given equation, away from all the variables. Factor the leading coefficient out of all terms in front of the set of parentheses. Divide the remaining linear coefficient by two, but only in your head. Square the answer from Step 3 and add that inside the parentheses.
- Draw the
**vector**. Showing That Two**Vectors**Are Equal Show that**vector**v with initial point at (5, −3) and terminal point at (−1, 2) is equal to**vector**u with initial point at (−1, −3) and terminal point at (−7, 2). Draw the position**vector**on the same grid as v and u. Next, find the magnitude and direction of each**vector**. **practice****problem**4 One unfortunate winter day I happened to slip on an icy ramp inclined 37° to the horizontal. Find my acceleration down the ramp given that the acceleration due to gravity points straight down and has a value of 9.8 m/s 2 .- Step 2: Now that you have the formula for velocity, you can find the instantaneous velocity at any point. For the example, we will find the instantaneous velocity at 0, which is also referred to as the initial velocity. v (0) = 3* (0 2) + 2* (0) + 1 = 1. This indicates the instantaneous velocity at 0 is 1. If you need to find the instantaneous ...
