Question

PLEASE HELP ME I AM STUCK, FRUSTRATED, AND DONT EVEN KNOW HOW TO START THIS PROBLEM AHHSRFHRERHYT

Answer 1

It takes the car 14 seconds to stop

Explanation:

A car is traveling at a constant velocity of 19 m/s when the driver puts

on the brakes to accelerate it at -1.4 m/s² until stopped

1. The initial velocity is 19 m/s

2. The acceleration is -1.4 m/s²

3. The final velocity is zero

We need to find how long it takes the car to stop

We can find the time by using the rule

→ v = u + a t

where v is the final velocity, u is the initial velocity, a is the

acceleration and t is the time

→ v = 0 m/s , u = 19 m/s , a = -1.4 m/s²

Substitute these values in the rule

→ 0 = 19 + (-1.4) t

→ 0 = 19 - 1.4 t

Add 1.4 t to both sides

→ 1.4 t = 19

Divide both sides by 1.4

→ t = 13.57 ≅ 14 seconds

It takes the car 14 seconds to stop
