A bus makes a trip according to the position-time graph shown in the drawing. What is the average velocity (magnitude and direction) of the bus during each of the segments A, B, and C? Express your answers in km/h. The scale for the time axis is 2 h per increment, and scale for the velocity axis is 210 km per increment. (Indicate direction by the sign of the velocity.) segment A segment B segment C km/h km/h km/h Show My Work (Optionall Time (h)

Based on the measured angles of the marble launcher, calculate the initial horizontal and vertical components of the marble’s velocity for each angle, assuming the velocity vector has the same magnitude as you calculated from Part I (4.31 m/s). angle 1: θ = 15° -->initial height 0.027m, horizontal distance 0.145m angle 2: θ = 45° -->initial height 0.027m, horizontal distance 0.209m angle 3: θ = 70° --> initial height 0.027m, horizontal distance 0.118m

A long distance commercial passenger plane flies North at 910 km/h. At the same time, there is wind of 30 km/h from the West. Use a scaled diagram, Pythagorean Theorem and trigonometry to answer the following . a) What is the magnitude of the resultant velocity?  b) What is the direction of the resultant ( North, South, East, West, NE, NW, SE or SW).  c). What is the angle of the resultant relative to due East? Round your answer to the nearest tenth.

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.

On a hot summer day, a young girl swings on a rope above the local swimming hole (Figure 1). When she lets go of the rope her initial velocity is 2.10 m/s at an angle of 35.0 ° above the horizontal. You may want to review (Pages 99 - 101). Part A If she is in flight for 0.611 S, how high above the water was she when she let go of the rope? ? h = Im

You first walk 10 meters at an angle of 30 degrees East of North. Then,you walk 15 meters at an angle of 45 degrees South of East. Assume that East is +x and North is+y, and assume you started at the origin (0,0).   A. Make a graph with x- and y-axes and draw your path on that graph (to scale, or at least asclose as you can get). Start the first vector at the origin, and the second vector at the tip ofthe first vector. Then, draw the resultant vector (their sum).   B. Break each part of the walk into their x- and y-components and then sum them to get thex- and y-components of the resultant vector. Make sure to include units and unit vectors.     C. What is your displacement from where you originally started?   D. If the whole walk took 40 seconds, then what was your average velocity

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 4.0 ss for the dart to land back at the barrel.     Part A What is the maximum horizontal range of your gun?

We want to find the coefficient of restitution e between the ball and the floor. We will be able to measure the time of flight between subsequent bounces, but not the velocities before and after each impact. Question 1 a. Using the kinematics equation for position, find a relationship between the time of flight tn and the velocity of the ball after the nth bounce. You should obtain a quadratic equation that has two solutions for the time tm, but only one of them represents the time of flight. b. Using the kinematics equation for velocity and the relationship determined in the previous step, find the relationship between the velocity right after the nth bounce and the velocity right before the (n +1)th bounce? c. Given your answers to the previous parts of this question and the definition of €, find the coefficient of restitution e in terms of the subsequent times of flight tn and tr+1.
