9. A soft drink distibutor drove west 11 km from Minnehaha to Nut Plains. She then turned around and drove back east for 209 km
guajiro [1.7K]

Answer:

220km

Explanation:

Given parameters:

Distance traveled from Minnehaha to Nut Plains  = 11km

Distance traveled to Dover  = 209km

Unknown:

The distance the soft drink distributor traveled  = ?

Solution:

To solve this problem, we  must understand that distance is the total length of path covered in a journey.

 So;

     Distance  = 209km + 11km  = 220km

The soft drink distributor covered 220km

The x and y coordinates of a particle at any time t are x = 5t - 3t2 and y = 5t respectively, where x and y are in meter and t i
allsm [11]

Answer:

v=\sqrt{26}~m/s

Explanation:

<u>Parametric Equation of the Velocity</u>

Given the position of the particle at any time t as

r(t) = (x(t),y(t))

The instantaneous velocity is the first derivative of the position:

v(t)=(v_x(t),v_y(t))=(x'(t),y'(t))

The speed can be calculated as the magnitude of the velocity:

v=\sqrt{v_x^2+v_y^2}

We are given the coordinates of the position of a particle as:

x=5t-3t^2

y=5t

The coordinates of the velocity are:

v_x(t)=(5t-3t^2)'=5-6t

v_y(t)=(5t)'=5

Evaluating at t=1 s:

v_x(1)=5-6(1)=-1

v_y(1)=5

The velocity is:

v=\sqrt{(-1)^2+5^2}

v=\sqrt{1+25}

\mathbf{v=\sqrt{26}~m/s}
