1. A car, starting from rest, accelerates in a straight path at a constant rate of 2.5 m/s². How
far will the car travel in 12 seconds?
20
m


Sagot :

Answer: 180 m

Explanation:

To find how far the car will travel, we can use the following kinematics equation:

d = v₀t + (1/2)at², where d is the distance traveled, v₀ is the initial velocity, a is acceleration, and t is the time.

Using the given information:

v₀ = 0, a = 2.5, t = 12

d = 0·12 + (1/2)(2.5)12²

d = 180 m

The car will travel 180 m.
