Question

a rock falling off the edge of a tall cliff falls 4.9t² meters in the first t seconds. evaluate 4.9t² for t = 6 to find the distance the rock would fall in the first 6 seconds. the rock would fall meters in the first 6 seconds.

Explanation:

Step1: Substitute t value

Given the formula $4.9t^{2}$, substitute $t = 6$. So we get $4.9\times6^{2}$.

Step2: Calculate the square

First, calculate $6^{2}=36$. Then the expression becomes $4.9\times36$.

Step3: Perform multiplication

$4.9\times36 = 176.4$.

Answer:

176.4
