- Why is (j + k) = i?I see that i x i = 0, that makes sense. But I thought that j x k = i? not j + k.arrow_forwardProblem 4: Two points in a plane have polar coordinates P1(2.4 m, Jt/6) and P2(3.8 m, 2jt/3). P1(, y) m 20% Part (a) Determine the x value of the Cartesian coordinates for Pj.arrow_forwardGiven that the acceleration vector is a(t)=(−16cos(−4t))i+(−16sin(−4t))j+(1t)k, the initial velocity is v(0)=i+k, and the initial position vector is r(0)=i+j+k, compute: A. The velocity vector v(t) B. The position vector r(t)arrow_forward

- A bottle rocket is launched straight up. Its height in feet (y) above the ground x seconds after launch is modeled by the quadratic function: y = -16x2 + 124x + 8. How many seconds did it take the rocket to strike the ground? O 8.59 seconds o 7.814 seconds 7.31 seconds O 8.295 seconds b narrow_forwardQ1\A: Consider these two vectors A-2i+3j+5k and B-5i+3j+10k, find the following C-A.Barrow_forwardFor the given vectors V₁ and V₂, determine V₁ + V2, V1 + V2, V1-V2, V1 V2, V₁ V₂. Consider the vectors to be nondimensional. Assume V₁ = 14, V₂ = 19, a = 3, b = 4,0 = 23° V₂ a Answers: V₁ + V₂ = V₁ + V₂ = i i V₁-V₂= (i V1 V₂ = V₁x V₂ = (i i Ө V₁ i+ i+ i+ i i i j+ i j+ j+ i i k) k) k)arrow_forward
- Given the following system of two equations: 9.5x+9.0y=2 3.0x+6.5y=9 Find x. Since D2L is limited to one answer per question, there is no way to enter both x and y.arrow_forwardVector C can be written (-3i+1j) cm O (-4i+2j) cm O (i-3j) cm (2i+-4j) cm 1 y (cm) 2 1 x (cm)arrow_forwardVectors A and B lie in an xy plane.
