6. During the last 10 seconds of the trip, the car slows down from a speed of 150 m/s to a stop- What is the deceleration of the car for those 10 seconds? Show work. Type here

Sagot :

time = 10 second.

initial speed = 150 m/s

final speed = 0

the deceleration of the car for 10 second is

[tex]=\frac{\text{ final speed - initial}}{\text{10 s}}[/tex][tex]\begin{gathered} =\frac{150-0}{10} \\ =15m/sec^2 \end{gathered}[/tex]

so the answer is 15 m/s2
