Question

  1. a car travels at 12 m/s and speeds up uniformly over the next 6 seconds.

a) find the acceleration 2 marks
b) find the velocity after 6 s. 2 marks

Explanation:

Step1: Recall acceleration formula

Acceleration $a=\frac{v - u}{t}$, where $u$ is initial velocity, $v$ is final velocity, $t$ is time. Here, assume the car moves with constant - acceleration motion. Given $u = 12\ m/s$, $t = 6\ s$. But we first need to find the displacement information to get the final velocity. Since the motion is uniformly - accelerated, we can also use the kinematic equation $s=ut+\frac{1}{2}at^{2}$. However, if we assume the information about displacement is not needed as we can use the basic acceleration formula with the given initial velocity and time for a simple case of constant acceleration. Let's assume the car moves with a constant acceleration and we use the formula $a=\frac{v - u}{t}$. First, we need to find the acceleration.
We know that for a uniformly - accelerated motion, if we assume the car starts with an initial velocity $u = 12\ m/s$ and the time $t = 6\ s$. If we assume the car moves with a constant acceleration and no other information about displacement is given, we can use the formula $a=\frac{v - u}{t}$. But if we assume the car moves with a constant acceleration and we know the initial velocity and time, and assume the car's motion is a simple uniformly - accelerated motion, we can use the formula $a=\frac{v - u}{t}$. Here, we assume the car moves with a constant acceleration and we use the formula $a=\frac{v - u}{t}$.
