Question

The position of a ball rolling in a straight line is given by x = 1.1 - 3.7t + 4.8t², where x is in meters and t is in seconds. What is the position of the ball at t = 2 seconds?

Answer 1

The position of the ball at t = 2 seconds is 12.9 meters.

Step-by-step explanation:

The position of the ball at t = 2 seconds can be found by substituting t = 2 seconds into the given equation: x = 1.1 - 3.7t + 4.8t².

So, x = 1.1 - 3.7(2) + 4.8(2)²

Simplifying the equation, we get:

x = 1.1 - 7.4 + 4.8(4)

x = 1.1 - 7.4 + 19.2

x = 12.9 meters
