The momentum of a 20 kilogram dog running at a speed of 8 meters per second is 160 (kg m/s). P=mv P=momentum m=mass v=velocity The units are (kg m/s). P=mv P= 20kg x 8 m/s P= 160 (kg m/s) .
momentum is the product of the velocity and mass: 250,000 kg m/s
The Kinetic energy (KE) of the go-cart can be calculated through knowing is mass and velocity. KE = 1/2 times both mass and velocity squared. The units are KE in joules, mass in kilograms, and velocity in meters per second. If you round to one significant figure this go-carts KE is 50-joules.
would be my dadde
The magnitude is 50.
360 kg/ms
200 joules at 20m/s
KE = 1/2*mass * velocity^2 KE = 1/2(14 kg)(3 m/s)^2 = 63 Joules
Momentum is just mass times velocity. We assume that given that you can do the arithmetic.
Kinetic energy = 1/2Mass x Velocity^2 KE = 1/2(1990) x (28^2) KE = 995 x 784 KE = 780080 Joules
Momentum = speed multiplied to mass. M'm = 5 ms^-1 X 20 kg . M'm = 100 kg m s^-1
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!
momentum is mass x velocity. If mass is 1 kg and velocity 1m/s then momentum is 1kgm/s
Density = mass / volume : Mass = volume * density : Volume = mass / densityDensity mild steel = 7.85 kg / litreSo >Mass = volume * density5 litres @ 7.85 kg per litre = 39.25 kilogramsAnd >Volume = mass / density5 kilograms / 7.85 = 0.637 litres
A medicine ball has a mass of 5 kg and is thrown with a speed of 2 ms What is its kinetic energy?KE = ½ * mass * velocity^2I'll let you take it from here!dude just answer the freakin question.
KE = 1/2mass * Velocity squared KE = 1/2(95 kg)(2.5 m/s)^2 = 297 Joules ( I think that needs to be trimmed to two significant figures )
The formula for kinetic energy is (1/2) x mass x velocity2. If mass is in kg. and speed in meters per second, the energy will come out in Joule.D. 125 J
