The demand for these things is very high. Everyone wants to have shelter, water, and food. However the demand for shelter is higher because water and food are more accessible.
Answer:
23.5 m/s
Explanation:
The velocity of the car in decelerated motion is given by
v = u + at
where
v = 0 is the final velocity
u is the initial velocity
a is the acceleration of the car
t = 3.0 s is the time it takes for the car to stop
The acceleration of the car is given by the frictional force, which is the only force acting on the car along the direction of motion, so:

where
is the coefficient of friction
Solving the previous equation for u, we find the initial velocity:

The Hawaiian Island was formation by volcanic activity
Answer:
F=0
Explanation:
Newton's second law states that the sum of the external forces is equal to the product of the mass and the acceleration of the body
F = m a
in this case it tells us that the velocity is constant so the acceleration must be zero,
therefore the sum of the external forces is zero; as they indicate that the surface is frictionless, there is no force applied to the system to maintain a constant speed
F = 0
