The wind velocity is 66 km/hour in the direction of N38°W. a) Write vectors (to the nearest tenth) representing the airplane A, the 884 km/hr wind W, and the aircraft relative to the ground R. 66 km/hr 389 1532 A = W Rarrow_forward@AB = 4 rad/s %AB = 6 rad/s² 0.5 m 45° B/C 1 m 60° IC Now let's look closer at Figure 2 from the prior question. By drawing lines that pass through points B and C which are perpendicular to their velocities (the red lines in the figure above) we can locate the IC at the intersection (the star). Now we can use some basic trig to figure out the distance TB/Ic labeled in the figure, which is the radial distance from the IC to point B. I've drawn in a green dashed line that creates two right triangles to help with the trig. What is the distance TB/IC?

- A snowboarder’s velocity is tracked by a pulse-laser velocimeter as she descends the slope. These velocity data are stored and analyzed via an embedded curve fitting procedure to determine a velocity function of v(t) = 1.5t2 + 2t + 2 (t is time in seconds and v is velocity in ft/s). At time equal 0, position (x) is zero. Find her position (e.g., distance traveled), velocity and acceleration formulations and values of each when time equals 15 seconds. Clearly write the formulas before finding respective values at t = 15 seconds!arrow_forward3. Use the graph of velocity vs. time below to answer the following questions.

- Q1/ The figure below shows such an LSPB trajectory, where the maximum velocity V 60 deg/sec. In this case, the times are given as t.= 5 sec and t 30 sec. In addition, the joint angles in beginning and the ending q=20 deg and qf = 70 deg , respectively. For these required data , determine the following : 1- The position function and its profile. 2- The velocity function and its profile. 3- The acceleration function and its profile. 4- The function of jerk variable and what is the nature of jerk? 5- The position, velocity, and acceleration at tm-13 sec. te tm ty te ty tarrow_forwardA docs.google.com In circular motion vr=0 vr=v theta vr=-v theta ar=0 The right representation of r-theta ***I' coordinates is --- a b. d a O b According to the figure, the vector 25 points equation isarrow_forwardFrom the image below, and using the given datum, match the variable expressions to their position coordinates, SA, SB and SC, where s A is for block A, $3 is for pulley B, and so is for pulley C.

Similarly the velocities of the two points are related by õp = bq + Up/Q- (2) The quantity õp/Q is the velocity of point P relative to point Q. I want you to use these ideas to solve the following problems. 1. The figure below shows a view from above of a large boat in the middle of the ocean. So that the crew on the ship can get exercise on long journeys, there is a circular walking/running track on the back deck.
