Explain how hurricanes can affect human life in Florida. Use complete sentences.

Physics
1 answer:
larisa86 [58]3 years ago
3 0

Florida is usually the state most affected by these storms because of its unique location. Florida is a peninsula with warm ocean currents on either side, which allows hurricanes to make land fall on either side of the state. Florida also receives variations of coastal and inland effects from hurricanes.

What is the volume in liters of the basketball?
babymother [125]

he basket ball diameter used by NBA men players is around 9.55 inches

So diameter = 9.55 inch = 0.243 m

So radius of basket ball = 0.1215 m

Volume , V=\frac{4}{3} \pi r^3

V = \frac{4}{3}* \pi *0.1215^3=0.0075 m^3=7.5 L

So volume of basket ball used by men NBA players = 7.5 L

A billiard ball of mass 0.28 kg hits a second, identical ball at a speed of 7.2 m/s and comes to rest as the second ball flies o
GaryK [48]

Answer:

(a) -8064 N

(b) 8064 N

Explanation:

(a)

From Newton’s law of motion, Force, F=ma where m is mass and a is acceleration.

Since acceleration is the rate of change of velocity per unit time, then where v is velocity and the subscripts f and I denote final and initial

For the first ball, the mass is 0.28 Kg, final velocity is zero since it finally comes to rest, t is 0.00025 s and initial velocity is given as 7.2 s. Substituting these values we obtain

F=0.28\times \frac {0-7.2}{0.00025}=-8064 N

(b)

For the second ball, the mass is also 0.28 Kg but its initial velocity is taken as zero, the final velocity of the second ball will be equal to the initial velocity of the second ball, that is 7.2 m/s and the time is also same, 0.00025 s. By substitution

F=0.28\times \frac {7.2-0}{0.00025}=8064 N

Here, we prove that action and reaction are equal and opposite

in what distance can a 1500kg automobile be stopped if the brake is applied when the speed is 20m/s and the coefficient of slidi
natali 33 [55]

1) The braking force is provided by the frictional force, which is given by:

F_f=\mu m g

where

\mu=0.7 is the coefficient of friction

m=1500 kg is the mass of the car

g=9.81 m/s^2 is the gravitational acceleration


Substituting numbers into the equation, we find

F_f= (0.7)(1500 kg)(9.81 m/s^2)=10301 N


2) The work done by the frictional force to stop the car is equal to the product between the force and the distance d:

W=-F_fd (1)

where we put a negative sign because the force is in the opposite direction of the motion of the car.


3) For the work-energy theorem, the work done by the frictional force is equal to the variation of kinetic energy of the car:

\Delta K=K_f -K_i =W (2)

The final kinetic energy is zero, so the variation of kinetic energy is just equal to the initial kinetic energy of the car:

\Delta K=-K_i=-\frac{1}{2}mv^2=-\frac{1}{2}(1500 kg)(20 m/s)^2=-300000 J


4) By equalizing eq. (1) and (2), we find the distance, d:

-K_i = -Fd

d=\frac{K_i}{F}=\frac{300000 J}{10301 N}=29.1 m
