A skydiver is falling vertically downward toward the earth with a constant velocity. What can we conclude from this? O His veloc

ity is 9.8 m/s downward. The net force on him is equal to his weight. O His acceleration is not zero but it cannot be determined without more data O His acceleration is 9.8 m/s2 dwnward O The net force on him is zero.

Answer:

The net force on him is zero.

Explanation:

The velocity of skydiver is constant.

As we know that the acceleration is rate of change in velocity. So, here velocity os constant it means acceleration of skydiver is zero.

According to Newton's second law

Force acting on a body is equal to the product of mass and velocity of the body.

As acceleration is zero that means the net force acting on the body is zero.

Why do atoms move at different speeds depending on weather they are in liquids or solids?
kiruha [24]
Atoms move at different speeds because of different amounts of space between each other (lots of space in a liquid so they move faster then in a solid where there is almost no space)

the moon revolves around the earth in a nearly circular orbit kept by gravitational force exerted by the earth work done will be
rodikova [14]

Answer:

Zero because the applied force is perpendicular to the motion of the object.

No work is done on an object moving is a circular path about a central attractive force.

Any work done in such a case would result in a change in the orbit.

A highway patrolman traveling at the speed limit is passed by a car going 20 mph faster than the speed limit. After one minute,
Oksi-84 [34.3K]

Answer:

It will take 40 seconds to catch the speeding car

Explanation:

Initial speed of the patrolman = 55 mph

after one minute speed of patrol man = 115 mph

now acceleration of patrolman is given by

a = \frac{v_f - v_i}{t}

a = \frac{115 - 55}{1/60} = 3600 m/h^2

now at this acceleration the distance covered by patrolman in "t" time is given as

d = v_i t + \frac{1}{2}at^2

d = 55t + 1800t^2

now we know the speed of the speeding car is given as

v' = (55+20) mph

now in the same time distance covered by it

d = 75 t

now since the distance covered is same

75 t = 55t + 1800 t^2

t = \frac{20}{1800} = \frac{1}{90} h

t = 40 seconds
