The momentum of a bowling ball decreases by 0.5 kg meters per second when it hits some pins How much momentum did the pins gain Explain?
0.5 kg m/s by the law of conservation of momentum
A 3-kg mass is in free fall. What is the velocity of the mass after 7 seconds?
69 m/s
A 3-kg mass is in free fall What is the velocity of the mass after 7 seconds?
69 m/s
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
Which has more kinetic energy a 0.0020-kg bullet traveling at 400 ms or a 6.4 X 10 7 -kg ocean liner traveling at 10 ms 20 knots?
Let's see. KE = 1/2mV^2 Bullet: KE = 1/2(0.0020 kg)(400 m/s)^2 = 160 Joules ------------------------------- Ocean Liner: KE = 1/2(6.4 X 10^7 kg)(10 m/s)^2 = 3.2 X 10^9 Joules ----------------------------- The linear by a long shot!
What is the size and direction of the final velocity of the tow cars if a 0.4 kg toy train car moving forward t 3 ms collides with and sticks to 0.8 kg toy car that is traveling in the opposite way?
0.4 kg(3 m/s) + 0.8kg(-2 m/s) = 1.2 kg m/s -1.6 kg m/s = -0.4 kg m/s -0.4 kg m/s = 1.2 kg(v) = (-0.4 kg m/s)/(1.2 kg) = v = -0.33 m/s the cars are traveling at 0.33 m/s in the direction of the second car.
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 180kg divide by 5s?
36
What is the momentum of 4 kg ball that is moving at the velocity of 2 ms?
(4 kg)*(2 m/s) = 8 kg•m/s
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
If a car has a mass of 400 kg and a velocity of 30 ms to the east what is the magnitude?
12,000 kg-m/s
How much does a 7 kg bowling ball weigh in newtons?
F=ma F=7kg*9.81m/s**2 F=68.67N
