Make a drawing of the path of an object in circular motion at constant speed. On that path, use a dot to represent the object’s position at time t1. Label this point as O, and draw a vector at O to represent the magnitude and direction of the object’s velocity at time t1. Draw another dot to represent the object’s position at a later time t2, shortly after t1, and label this point P. Draw a vector at P to show the magnitude and direction of the object’s velocity at time t2.

Use the fact that the lengths of displacement and velocity vectors are proportional to each other to draw a series of vectors that are proportional to the average x and y-velocity vector components during each 1/15th of a second time interval. Start with Frame 1 in each of the figures that follow. Place the tail of the first velocity vector at the ball’s location in frame 1 and then place the tail of the next vector at the ball’s location in frame 2 and so on.arrow_forward

Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. b. What angle ϕ gives the maximum range, measured along the incline? Ignore air resistance. c. Since there's no air resistance, this is a problem in projectile motion. The goal is to find the point where the ball's parabolic trajectory intersects the incline. It is best to choose the x-axis to be horizontal and direct to the right, the y-axis to be vertical and direct to the up, and the origin to be at the point where the ball is fired. In the projectile equations, the launch angle α0 is measured from the horizontal. What is this angle in terms of (θ) and (ϕ)?arrow_forwardThis is a two part problem.

- The diagram below is comprised of four vectors A, B. C and D. Using addition and subtraction of vectors, describe the following: D A B Note: your answer should be an algebraic expression comprising of A, B. C and D. Make sure to take note of the positions of the tails and heads of each vector. B = 0 = |(i.e., when you add the vectors together, they cancel and equal 0)arrow_forwardPart B As stated in the strategy, choose a coordinate system where the x axis is horizontal and the y axis is vertical. Note that in the strategy, the y component of the projectile's acceleration, ay, is taken to be negative. This implies that the positive y axis is upward. Use the same convention for your y axis, and take the positive x axis to be to the right. Where you choose your origin doesn't change the answer to the question, but choosing an origin can make a problem easier to solve (even if only a bit). Usually it is nice if the majority of the quantities you are given and the quantity you are trying to solve for take positive values relative to your chosen origin.

Draw the ball in at least five different positions; two when the ball is going up, two when it is going down, and one at its maximum height. Label the horizontal and vertical axes of your coordinate system. On your sketch, draw and label the expected acceleration vectors of the ball (relative sizes and directions) for the five different positions. Decompose each acceleration vector into its vertical and horizontal components. On your sketch, draw and label the velocity vectors of the object at the same positions you chose to draw your acceleration vectors. Decomposes each velocity vector into its vertical and horizontal components. Check to see that the changes in the velocity vector are consistent with the acceleration vectors.arrow_forward
