Problem-Solving Technique: Draw a labeled picture. Put a coordinate system on the picture indicating the location of the origin and the positive direction. Show the solution in a step-by-step orderly fashion. Write any equation you use in symbolic form before substituting in numbers. 1. Ann is traveling at 30 m/s (80 mi/hr) west when she passes a police car. She immediately begins slowing down at a rate of 2.5 m/s for 4 seconds. How far has she traveled for this time? a. Fill in the information that is given in the problem. Put a question mark for any quantity that is not given in the problem. Vox = v. = b. Determine the distance she traveled in this time. Start with the equation in sy numbers you used including units. olic form and show the
1. Draw a diagram for the vectors and answer the question.A. From the same starting point, vector x is moving northeast while vector y is moving southward. Determine the direction/position of vector y with respect to vector x. B. Vector A is moving from the east while Vector B is moving southeast. At certain time t, the two vectors are bound to meet (in a 2d graph, B is above A and is approaching A). What is the position of B relative to A.
include a picture or description of your coordinate system (origin, positive direction).

A ball is thrown at an initial height of 90 feet at an initial velocity of 55 feet/second at an angle of 75 degrees. Given the parametric equations y = 16t2 + Vo · Sin(0)t + ho and r = Vo Cos(0)t. When doing calculations, carry 5 digits of accuracy, so your round off does not build up. a. What is the ball's height in 3 seconds? feet. b. When will the object hit the ground? seconds. c. How far horizontally will the ball be when it hits the ground? feet. d. When will the ball be at its maximum height? seconds. e. What is the ball's maximum height? feet. f. How far horizontally will the ball be when it reaches its maximum height? feet
A truck flew off the freeway and crashed into the side of the Mission Valley Dave & Busters. When the truck broke through the guardrail it was launched from the freeway with a horizontal velocity of 10.7 m/s and fell a vertical distance of 50 feet (15.2 m). a) Draw a simplified sketch showing the trajectory of the truck being launched horizontally with the velocity of 10.7 m/s. b) Determine the time that it would take for the truck to freefall the 50 feet(15.2 m). c) Ignoring air resistance and scraping the building on the way down, determine the instantaneous velocity of the truck just before impacting the ground.
4. A jogger warms up by running 350 meters east at an average speed of 3.8 m/s, then running west 240 meters at an average speed of 4.2 m/s. a. How much time does the first part of the trip take? b. How much time does the second part of the trip take? c. How long does the entire trip take? d. What is the total distance for the entire trip? e. What is the magnitude of the jogger's displacement for the entire trip? f. What is the average speed for the entire trip? g. What is the magnitude of the jogger's average velocity for the entire trip?
A test gunshot was fired at an initial velocity of 160 m/s and an angle of 60° at the top of a 180 m tall building. Neglecting air resistance, determine the following and draw the figure. The maximum height above the level ground that can be reached by the bullet. The time for the bullet to hit the ground. The velocity with which the bullet will hit the ground.
