Answer to Question #210888 in Mechanics | Relativity for Keightcolin

Question

A car starts from stoplight and is traveling with a velocity of 10m/second east in 20 seconds. What is the acceleration of the car?

Answer 1

Solution.

$v_0=0;$

$v=10m/s;$

$t=20s;$

$a=\dfrac{v-v_0}{t};$

$a=\dfrac{10m/s-0}{20s}=0.5v/s^2;$

Answer: $a=0.5m/s^2.$
