Answer:
19.4 seconds
Explanation:
We have:
m: mass of the car = 1500 kg
v₀: is the initial speed = 19 m/s
: is the final speed = 0 (it stops)
: is the coefficient of kinetic friction = 0.100
First, we need to find the acceleration by using the second Newton's law:


Solving for a:

Now we can find the time until it stops:

Solving for t:

Therefore, the time until it stops is 19.4 seconds.
I hope it helps you!
Answer:
5kgm
Explanation:
convert cm to m and g to kg
250/1000=0.25kg
5/1000=0.05m
then find the density
density=mass/volume
=0.25kg/0.05m
=5kgm
