1 Putt Putt Golf A golfer takes three strokes to get his ball in the hole after landing on the green. The first shot moves the ball 18 ft due east, the second 12 ft southwest, and the third 2.0 ft due north, and into the hole. (a) Draw a picture. Your picture should include an origin and labels for axes. It should indicate the starting position of the ball and the location of the hole, and it should clearly indicate all three shots. It should be drawn to scale, and the directions of the shots should be accurate. (b) What shot – distance and direction – would have allowed the golfer to sink the putt in a single attempt? If you give an angle, clearly indicate what that angle means. ("60" is meaningless. "60' west of north" is clear. "60° north of west" is also clear, but means something different.)

Question 20 A helicopter is heading S 43° E (i.e. direction angle of 313°) with an airspeed of 27 mph, and the wind is blowing S 13° E (i.e. direction angle of 283°) at 10 mph. Helicopter's speed Round all numbers in your answers below to 2 places after the decimal point. (a) Find the velocity vector that represents the true heading of the helicopter. Type your answer in component form, (where a and b represent some numbers). Velocity vector of helicopter's true heading: (b) Find the helicopter's speed relative to the ground (in mph). mph (c) Find the helicopter's drift angle, 8. (The drift angle is the number of degrees that the helicopter will end up flying off-course.) 8 = Submit Question degrees

Please help with parts g and h Two velocity vectors are defined as follows: v1 = 40.0 m/s, 50.0 degrees cw from the +x axis v2 = 30.0 m/s, 75.0degrees cw from the -y axis d) Calculate the x- and y-components of v2. Write the vector v2 in terms of its components using unit vector notation. e) Calculate the x- and y-components of the change in velocity defined as Δv= v2-v1. Write the vector Δv in terms of its components using unit vector notation. f) Sketch the vector Δv on an x-y grid. Define a relevant angle symbolically whose numerical value you will calculate in the next part. g) Calculate the magnitude and direction of the vector Δv. h) Finally, write the vector Δv in terms of its magnitude and direction.
3. A hiker walks 1.5 km at an angle of 48 degrees north of east 7, and then hikes 3.0 km at an angle of 30 degrees north of west . What is the displacement of the hiker from the origin (magnitude and direction)? Determine the magnitude and direction by adding the vectors graphically and mathematically. Be sure to attach your graph. Magnitude (from graph): Direction (from graph): Magnitude (mathematical): Direction (mathematical):

#1 Consider two vectors: E1 with magnitude 7 N/C and at an angle of 20 degrees above the positive xdirection, and E2 with magnitude 5 N/C and at an angle of 30 degrees to the left of the positive ydirection. (a) Visualizing vector sums: Draw a vector sum diagram illustrating the sum EN = E1 + E2 andanother of the vector difference E1 = EN − E2. Make sure to label your arrows. Please makethe diagram as close to scale as possible (use a ruler to measure, or use a program that lets youdraw accurately.) (b) Interpreting vector diagrams: From the diagram, should the magnitude of the sum be larger orsmaller than 7 N/C? From the diagram, predict the general direction of the sum, within 1/8 ofa circle (for instance, between 0 and 45 degrees above the x axis, etc.) Note, this is one goodway to check your own answers when working with vectors. (c) Calculating vector components and sums: Compute the components and then the magnitude anddirection of the sum. For direction, we want the angle…

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.
