Find parametric equations that describe the circular path of the following object. Assume​ (x,y) denotes the position of the object relative to the origin at the center of the circle. Use the units of time given in the description. A​ go-cart moves counterclockwise with constant speed around a circular track of radius 300 ​m, completing one lap in 1.7 min. Assume the center of the track is at the origin and that the​ go-cart starts at (300 comma 0 ). What are the parametric​ equations?

Answer:

the parametric equations for the circular path are

x= 300 m *cos (3.695 min⁻¹ t)

y= (-300 m) *sin(3.695 min⁻¹ t)

Step-by-step explanation:

the parametric equations of the go-kart are

x= R*cos (ω*t)

y= R*sin (-ω*t)= -R*sin(ω*t) ( since the rotation is counterclockwise)

where R= radius , ω= angular velocity , x₀ and y₀ are the initial position in the x- axis and y- axis respectively and the parameter t= time ( in minutes)

since

R= 300 m

ω= 2π/ 1.7 min = 3.695 min⁻¹

therefore the equations for the circular path are

x= 300 m *cos (3.695 min⁻¹ t)

y= (-300 m) *sin(3.695 min⁻¹ t)
