Question

1. lillian has had enough of tiffanys antics and high jinks and walks over to tiffanys table. with an initial speed of 2 m/s, lillian accelerates at a rate of 18 m/s/s for 1.5 seconds, what is her final speed?

Explanation:

Step1: Identify the kinematic - equation used

The equation for final speed is $v = v_0+at$, where $v$ is final speed, $v_0$ is initial speed, $a$ is acceleration and $t$ is time.

Step2: Substitute the given values

Given $v_0 = 2\ m/s$, $a = 18\ m/s^2$, and $t = 1.5\ s$. Substitute into the formula: $v=2 + 18\times1.5$.

Step3: Calculate the result

First, calculate $18\times1.5=27$. Then, $v=2 + 27=29\ m/s$.

Answer:

$29\ m/s$
