Ayuda Porfavor se los agradeceria mucho. Metodo del poligono 1. Sea d1⃗⃗⃗⃗ → el desplazamiento de una persona al caminar 50m directamente hacia el Este y d2→ el desplazamiento cuando cambia de rumbo caminando otros 40m a 500 al Norte del Este.

Determine:

a) El desplazamiento total de dicha persona.

b) La dirección del desplazamiento resultante.

Toma en cuenta:

Escala 1cm = 10 cm

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.

This is the number of complete movements of a wave per second.
