a = <1,2>
v = <t+c1,2t+c2>
v(0) = <0,0> so c1=c2=0
v = <t,2t>
r = <1/2 t^2+c1, t^2+c2>
r(0) = <1,0> so c1=1, c2=0
t = <1/2 t^2+1, t^2>
Please give explanation and show work. Thank you so much!
v = <t+c1,2t+c2>
v(0) = <0,0> so c1=c2=0
v = <t,2t>
r = <1/2 t^2+c1, t^2+c2>
r(0) = <1,0> so c1=1, c2=0
t = <1/2 t^2+1, t^2>
x(t) = x0 + v0t + (1/2)at^2
where x(t) is the position vector at time t, x0 is the initial position vector, v0 is the initial velocity vector, a is the acceleration vector, and t is the time.
In this case, we are given the following values:
a = (1, 2),
v0 = (0, 0),
x0 = (1, 0).
Substituting the given values into the equation, we get:
x(t) = (1, 0) + (0, 0)t + (1/2)(1, 2)t^2
Since t = 0 gives us the initial position vector, we can ignore the (0, 0)t term.
So the position vector at any time t is:
x(t) = (1, 0) + (1/2)(1, 2)t^2
Simplifying the equation, we get:
x(t) = (1 + (1/2)t^2, (1/2)t^2)
Therefore, the position vector of the particle is (1 + (1/2)t^2, (1/2)t^2).
