A 2000 kg car is driving at 5 m/s on wet asphalt, but then makes a turn on some ice and loses control. The driver applies brakes
and the rubber tires skid on the ice until the car comes to rest. Thankfully there was no crash.

Answer:
10,000kgm/s
Explanation:
Since we not told what to look for, we can as well find the momentum of the car.
momentum = mas * velocity
Given
Mass of the car = 2000kg
velocity = 5m/s
Substitute into the formula
Momentum = 2000 * 5
Momentum = 10000kgm/s
Hence the momentum of the car is 10,000kgm/s

Explanation:
Answer:
fluid transfer of heat by the motion of the particles of gas or fluid
Time taken by the package to reach the sea level= 13.7 s
height=h=925 m
initial velocity along vertical= vi=0
acceleration due to gravity=g=9.8 m/s^2
using the kinematic equation h= Vi*t + 1/2 gt^2
925=0(t)+1/2 (9.8)t^2
4.9 t^2=925
t= 13.7 s
'A' is correct. B, C, and D are false statements.
In order to design an experiment, you need a hypothesis about the scientific question you are trying to answer.
