Soccer player #1 is 8.50 m from the goal, as the figure shows. If she kicks the ball directly into the net, the ball has a displacement labeled 7. If, on the other hand, she first kicks it to player #2, who then kicks it into the net, the ball undergoes two successive displacements, y and x. What are the magnitudes of (a) x, and (b) jy. 30.0 Net 90° (a) Number i Units (b) Number i Units <> <>

Q/ A particle moves in an xy plane according to x(1)= -20.00 + 20.00t - 4.00 and y(t) = 25.00 + 17.00t -19.00², with x and y in meters and t in seconds. At t= 10 s, a. What is the particle velocity vector vì nunit vector notation? b. What is the particle acceleration vector đìn unit vector notation?

A jet is flying at a speed of 760 mi/hr relative to the air, and in the direction N 30°W. A wind is blowing 48 mi/hr in the direction N 45°E. (If needed, round to two decimal places.) a) Express the velocity of the wind as a vector in component form. b) Express the velocity of the jet relative to the air as a vector in component form. c) Find the true velocity of the jet as a vector in component form. d) Find the true speed of the jet. 35%

= 3.98 m to the north, A novice golfer on the green takes three strokes to sink the ball. The successive displacements of the ball are d₁ d₂ = 2.06 m northeast, and d3 = 1.16 m at 30.0° west of south (see the figure below). Starting at the same initial point, an expert golfer could make the hole in what single displacement? magnitude direction WE S m o north of east d₂ d₁ 30.0° dz

B) what is the position vector ? r(t)

A turtle ambles leisurely from a location with position vector r1,x = 1.87 m and ri.y = -2.95 m in a lettuce garden to another location with position vector r2.x = 3.91 m and r2.y = -4.27 m, where the lettuce appears to be tastier. The excursion takes 5.17 min to complete. What are the components and the magnitude of the turtle's average velocity in meters per second? Vav,x m/s Vav,y m/s %3D m/s %3D
