a car traveling at 28 m/s slows down at a constant rate for 4 seconds until it stops. what is its acceleration?
astra-53 [7]
We are given the following conditions:
v_{0} = 28m/s&#10;&#10;t = 4s&#10;&#10;v_{f} = 0m/s

Since we are told it slows down at a constant rate, we know we are dealing with uniformed accelerated motion, or UAM for short.

So we look at our kinematics equation that contains the given variables.

v_f = v_0 + at

This contains our target variable and our initial conditions. Plug and chug, we get:

(0m/s) = (28m/s) + a(4s) -28m/s = (4s)*a a = -7m/s^2

Thus the answer is:

a = -7m/s^2

Hope this helps!

Answer:

Without plants producing oxygen, no creatures would be able to breath and would thus die off. With no creatures breathing, and thus producing no carbon dioxide, plants would starve off and die since they require carbon dioxide to live.

densk [106]

Here when car in front of us applied brakes then it is slowing down due to frictional force on it

So here we can say that friction force on the car front of our car is given as

F_f = \mu m g

So the acceleration of car due to friction is given as

F_{net} = - \mu mg

a = \frac{F_{net}}{m}

a = -\mu g

now it is given that

\mu = 0.868

g = 9.81 m/s^2

so here we have

a = -0.868 * 9.81

a = -8.52 m/s^2

so the car will accelerate due to brakes by a = - 8.52 m/s^2
