A bird flies from the south pole to the north pole. Part of the journey is 1000 miles that takes two weeks. What is the birds Ve
alexira [117]
Formula for Velocity = DISTANCE traveled/TIME to travel distance + direction

For this one, we can use mph(miles per hour) as unit. 

v = 1,000 miles / 336 hours   (2 weeks = 24 hours  x 14 days = 336 hrs)
   = 2.98 mph North

or we can use kph (kilometers per hour)

v = 1609.34 km / 336 hours    (1 mile = 1.60934 km)
  = 4.79 kph North

Suppose that a constant force is applied to an object with a mass of 12kg, it’s creates an acceleration of 5m/s^2. The accelerat
Klio2033 [76]

Answer:

Mass of second object will be 15 kg

Explanation:

We have given mass of first object = 12 kg

Acceleration a=5m/sec^2

According to second law of motion we know that force F = MA

So force F=12\times 5=60N

As the same force is applied to the second object of acceleration a=4m/Sec^2

So force = ma

60=m\times 4

m = 15 kg

So mass of second object will be 15 kg

Mass and Weight: What is the mass of an object that experiences a gravitational force of 685 N near Earth's surface where g
11Alexandr11 [23.1K]

Answer:

m = 69.9 kg

Explanation:

The mass and the weight of an object are two different quantities. Mass is basically the amount of matter that is present in a body. It remains same everywhere in the universe and measured in kilograms.

Weight is basically a force. It is the force by which earth attracts everything towards itself. The weight of an object changes from planet to planet, with the change in value of the gravitational acceleration (g).

Therefore, the relation between mass and weight of an object is given by the following formula:

W = mg

m = W/g

where,

m = mass = ?

W = Weight = 685 N

g = 9.8 m/s²

Therefore,

m = (685 N)/(9.8 m/s²)

<u>m = 69.9 kg</u>
