Answer to Question #87494 in Mechanics | Relativity for Amoo Emmanuel

Question

A car of mass 500kg accelerates from rest at 1m/s². What is the total distance covered in 1 minute?

Answer 1

We can find the total distance covered in 1 minute from the kinematic equation:

$$s = v_0t + \dfrac{1}{2}at^2,$$

here, $s$ is the total distance covered in 1 minute, $v_0 = 0$ is the initial velocity of the car, $a$ is the acceleration of the car and $t$ is time.

Then, we get:

$$s = v_0t + \dfrac{1}{2}at^2 = 0 \dfrac{m}{s} \cdot 60 s + \dfrac{1}{2} \cdot 1 \dfrac{m}{s^2} \cdot (60 s)^2 = 1800 m.$$

Answer:

$s = 1800 m.$
