If a 100 kg man was running at 15 mph what is his momentum?
momentum change = 670.56 kilogram-meter/second
What is momentum a mearsure of?
Momentum is a measure of how much force it takes to stop something in a certain amount of time. If it takes 10 N to stop object A in 30 sec and it takes 15 N to stop object B in 30 sec, then B has more momentum; 50% more momentum.
A 4.5kg ham is thrown into a stationary 15 kg shop cart At what speed will the cart travel if the ham had an initial speed of 2.2 ms?
m = 4.5kg v = 2.2m/s M = 15kg V = ? ---- velocity of ham and cart before: momentum of ham = pv momentum of cart = 0 after: momentum of ham and cart = (m+M)V momentum of ham + momentum of cart = momentum of ham and cart mv + 0 = (m+M)V mv / (m+M) = V (4.5*2.2) / (4.5 + 15) = 0.51 kgm/s
When a rifle is fired it recoils as the bullet is set in motion the bullet is ideally acquire equal?
And opposite momentum. Say bullet muzzle velocity = 15 000 metres per second Say bullet mass = 0.02 kilogram (20 grams) Say rifle mass = 3 kilogram Then > Bullet momentum = 0.02 * 15 000 = 300 kg - m/s Presume Rifle momentum the same , then 300 = 3 * ? ? = 100 metres per second
What is the force exerted by a cather's glove on a 0.15-kg baseball moving at 35ms that is stopped in 0.02 s?
First, multiply mass x velocity, to get the momentum.The momentum in this case is also equal in magnitude to the impulse, which is the change of momentum - since all the momentum gets canceled. Since impulse is also time x force, you can divide the momentum, or impulse, by the time, to get the force. Due to the units used, the answer will of course be in newton.
How much does a sledgehammer cost?
They come in different weights and prices but a good Stanley 8 pound sledgehammer sells for aprox $30.
What is the momentum of a bird with a mass of 0.018 kg flying at 15 ms?
The momentum is the product of the mass and the velocity.

Is hitting your head at 15 miles per hour the same force of impact as a sledgehammer?
It can be. Hitting your head at 15 m/hr can hurt quite a bit. It is about the same force as landing on your head after falling from a tall staircase. Potentially lethal
