A bird is flying north with a mass of 2.5 kg has a momentum of 17.5 kg ms. at what velocity is it flying?
The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the bird's momentum is 17.5 kg m/s and its mass is 2.5 kg. To find the velocity, divide the momentum by the mass: 17.5 kg m/s / 2.5 kg = 7 m/s. Therefore, the bird is flying at a velocity of 7 m/s.
What is mass in kg if the weight is 7 newtons?
To find the mass in kilograms when weight is given in newtons, you can use the formula: mass (kg) = weight (N) / acceleration due to gravity (9.81 m/s^2). Therefore, if the weight is 7 newtons, the mass would be 0.71 kg approximately (7 N / 9.81 m/s^2).
What is the momentum of a 7 kg object that is moving with a speed of 3 ms?
The momentum of the object can be calculated using the formula: momentum = mass x velocity. Plugging in the values, momentum = 7 kg x 3 m/s = 21 kg m/s.
A 3-kg mass is in free fall. What is the velocity of the mass after 7 seconds?
69 m/s
How much force is needed to accelerate a 1000 kg car at a rate of 7 ms 2?
The force needed to accelerate the 1000 kg car at a rate of 7 m/s^2 can be calculated using Newton's second law, which states that force is equal to mass times acceleration. Therefore, the force required would be 7000 Newtons (1000 kg * 7 m/s^2).
Which has more momentum a 3.0 kg sledgehammer swung at 2 ms or a 4.0 kg sledgehammer swung at 1.5 ms?
The momentum of an object is given by the equation momentum = mass x velocity. Comparing the two scenarios, the momentum of the 3.0 kg sledgehammer swung at 2 m/s would be more (momentum = 6.0 kg m/s) compared to the 4.0 kg sledgehammer swung at 1.5 m/s (momentum = 6.0 kg m/s).
In an isolated system Bicycle 1 and Bicycle 2 each with a mass of 15 kg collide. Bicycle 1 was moving to the right at 1 ms while Bicycle 2 was moving to the left at 3 ms. What is the magnitude of thei?
60 kg-m/s Just took the test
What is the gravitational potential energy of a ceiling fan that has a mass of 7 kg and is 4 m above the ground?
The gravitational potential energy of the ceiling fan can be calculated using the formula: GPE = mgh, where m is the mass (7 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (4 m). Plugging in the values: GPE = 7 kg * 9.81 m/s^2 * 4 m = 274.68 Joules.
1 kg watt is equal to how many newtons?
I don't think there is any equivalency.... A watt isW = J/s = (N*m)/s = ((kg*(m/s^2))*m)/s = kg*(m^2))/(s^3)Therefore: W*kg = (kg^2)*((m^2)/(s^3)) which is not equal to N = kg*(m/s^2)I guess the closest answer would be :1 kg*W = (1 kg*m/s) N or1 kg*W = (1 N*s) N
What is 180kg divide by 5s?

How much potential energy does a 7 kg bowling ball have when it is held 1 meter off the ground?
The potential energy of the bowling ball is given by the formula PE = mgh, where m is the mass (7 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (1 meter). Substituting the values, the potential energy is calculated as PE = 7 kg * 9.81 m/s^2 * 1 m = 68.67 J.
what is the momentum of a 1400kg car traveling at 25 m/s?
The momentum of a 1400 kg car traveling at 25 m/s is: momentum = mass x velocity momentum = 1400 kg x 25 m/s momentum = 35,000 kg m/s Therefore, the momentum of the 1400 kg car traveling at 25 m/s is 35,000 kg m/s
