Where I had $480 he used 2/3 of it to buy an electric van he also bought a tea set for $60 how
yawa3891 [41]

2/3 of 480 is 480 divided by 3 and that number times 2, which is 320. The man or woman probably used $60 of this to buy the tea set, which leaves them with $260.

Use a(t) = −9.8 meters per second per second as the acceleration due to gravity. (Neglect air resistance.) A canyon is 2100 mete
Umnica [9.8K]

Answer:

t \approx 20.7\,s

Step-by-step explanation:

Given that rock experiments a constant acceleration, position function can be obtained by integrating twice:

v(t) = v_{o} - a\cdot t

s(t) = s_{o} + v_{o}\cdot t -\frac{a}{2}\cdot t^{2}

The initial conditions of the rock are, respectively:

s_{o} = 2100\,m

v_{o} = 0\,\frac{m}{s}

Position of the rock as a function of time is:

s(t) = 2100\,m -(4.9\,\frac{m}{s^{2}})\cdot t^{2}

The time taken for the rock to hit the canyon floor is:

0\,m = 2100\,m - (4.9\,\frac{m}{s^{2}} )\cdot t^{2}

2100\,m = (4.9\,\frac{m}{s^{2}} )\cdot t^{2}

t = \sqrt{\frac{2100\,m}{4.9\,\frac{m}{s^{2}} } }

t \approx 20.7\,s
