Question 1: Palette 1/2

Resnick Haliday MCQ

Concept: The change in position (displacement $\Delta x$) of a particle moving in one dimension over a time interval $t_1$ to $t_2$ is equal to the area under the velocity-time graph $v_x(t)$ between $t_1$ and $t_2$:
$\Delta x = x(t_2) - x(t_1) = \int_{t_1}^{t_2} v_x(t) \, dt$

$v_x$ is the velocity of a particle moving along the $x$-axis as shown in the figure. If $x = 2.0\text{ m}$ at $t = 1.0\text{ s}$, what is the position of the particle at $t = 6.0\text{ s}$?

$-2.0\text{ m}$

$+2.0\text{ m}$

$+1.0\text{ m}$

$-1.0\text{ m}$

Question 2: Palette 2/2

Resnick Haliday MCQ

Concept: Average acceleration $a_{\text{avg}}$ is defined as the change in velocity $\Delta v$ divided by the total time interval $\Delta t$:
$a_{\text{avg}} = \frac{v_f - v_i}{\Delta t}$
where $v_i$ is the initial velocity and $v_f$ is the final velocity.

What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of $8.0\text{ m/s}$ when going down a slope for $5.0\text{ s}$?

$1.1\text{ m/s}^2$

$1.9\text{ m/s}^2$

$1.6\text{ m/s}^2$

$0.85\text{ m/s}^2$
