What happens when two carts of equal mass one moving and one at rest collide in an elastic collision?

What happens when two carts of equal mass one moving and one at rest collide in an elastic collision? If one cart is initially at rest, say m2, then we have m1v1i = (m1 + m2)vf, and vf = m1v1i/(m1 + m2). If the two initial momenta are equal and opposite, they exactly cancel, and […]

Which has more momentum a large truck moving at 30 mph or small truck moving at 30 mph?

Which has more momentum a large truck moving at 30 mph or small truck moving at 30 mph? Expert-Verified Answer So you can see that if the mass increases, also does the momentum, so if both trucks move at the same velocity, then the truck with the bigger mas will have a bigger momentum. Which

Is dropping a box causes it to accelerate downward this statement is an example of Newton’s first law of motion?

Is dropping a box causes it to accelerate downward this statement is an example of Newton’s first law of motion? Dropping a box causes it to accelerate downwards. The answer Dropping a box causes it to accelerate downwards refers to a box with a force acting upon it—the force of gravity. Also, the box is

When a bullet of mass 10 gram moving with a velocity of 400 metre per second gets embedded?

When a bullet of mass 10 gram moving with a velocity of 400 metre per second gets embedded? Thus, the velocity acquired by the wooden block (having the bullet embedded in it) is 4.4 metres per second. How do you find kinetic energy from calories? – Kinetic energy is given as, $K.E.=\dfrac{3}{2}nRT$ where n is
