The ratios are all proportional to 50/1.
Ratios are proportional when its cross products are equal.
a/b = c/d where ad = cb
100/2 is proportional to 50/1 because 100*1 = 2*50 ⇒ 100 = 100
150/3 is proportional to 50/1 because 150*1 = 3*50 ⇒ 150 = 150
175/3.5 is proportional to 50/1 because 175*1 = 3.5*50 ⇒175 = 175
200/4 is proportional to 50/1 because 200*1 = 4*50 ⇒ 200 = 200
Answer:
Speed = 13.0m/s
Step-by-step explanation:
Given that velocity, v = (ai ± bj)m/s.
Because speed is scalar and has only magnitude, we can obtain it from the velocity by calculating only the magnitude given as:
...Equation 1
From the question, we were given the position vector, r
The velocity can be obtained by differentiating r with respect to time, t
We have that differentiation of a constant is 0.
At time t = 2.00s,
To obtain the speed, we use equation 1
<em>Therefore, the speed of the object at time t = 2.00s is 13.00m/s</em>
