Post Utme Futo 2022 Physics Objective / Multiple Choice
Question 21 POST_UTME_FUTO • 2022 • PHYSICS • objective

A particle of mass $m$ is projected from the origin with an initial velocity $mathbf{v}_0 = \( v_{0x}, v_{0y} \)$. If the particle experiences a cons\tant acceleration $mathbf{a} = \( a_x, a_y \)$, find the position vector $mathbf{r}(t)$ of the particle as a function of time $t$.

Answer Options

Correct Answer A. \mathbf{r}(t) = \left\( v_{0x}t + \frac{1}{2}a_xt^2, v_{0y}t + \frac{1}{2}a_yt^2\right \)
B. \mathbf{r}(t) = \left\( v_{0x}t - \frac{1}{2}a_xt^2, v_{0y}t - \frac{1}{2}a_yt^2\right \)
C. \mathbf{r}(t) = \left\( v_{0x}t + \frac{1}{2}a_xt^2, v_{0y}t - \frac{1}{2}a_yt^2\right \)
D. \mathbf{r}(t) = \left\( v_{0x}t - \frac{1}{2}a_xt^2, v_{0y}t + \frac{1}{2}a_yt^2\right \)
Correct Answer
A
Correct Option:
\mathbf{r}(t) = \left\( v_{0x}t + \frac{1}{2}a_xt^2, v_{0y}t + \frac{1}{2}a_yt^2\right \)
