Which of the following is true about the momentum of a large truck and a baby carriage rolling down a hill at the same time neglecting friction the baby carriage will have?

Which of the following is true about the momentum of a large truck and a baby carriage rolling down a hill at the same time neglecting friction the baby carriage will have?

Solution: If the truck and the baby carriage are rolling down the same initial position then at the bottom of the hill, they will have same velocity because velocity does not depend upon their mass. Therefore, at the bottom of the hill, the heavy truck will have more momentum and baby carriage will have less momentum.

When you jump from an elevated position you usually bend your knees upon reaching the ground?

Question: When you jump from an elevated position you usually bend your knees upon reaching the ground, which makes the time of the contact about 10 times that of a stiff-legged landing. In this way the average force your body experiences is Omore than 1/10 as great about 1/10 as great O less than 1/10 as great.

Which has the greater momentum when moving which has the greater momentum when moving?

The forward moving object will have the greatest momentum. An object with a changing speed will have a changing momentum.

When comparing the momentum of two moving objects which of the following is correct?

When comparing the momentum of two moving objects, which of the following is correct? The object with the higher velocity will have less momentum if the masses are equal. The more massive object will have less momentum if its velocity is greater.

Which has a greater momentum a heavy truck at rest or a moving skateboard?

Which has a greater momentum, a heavy truck at rest or a moving skateboard? A moving skateboard has a greater momentum than a heavy truck at rest.

Which has greater mass a heavy truck at rest or a rolling skateboard?

Which is inertia and which is inertia in motion? A heavy truck, even at rest, has the greater mass. Which has the greater mass: a heavy truck at rest or a rolling skateboard? The rolling skateboard, being the only one of the two in motion, has the greater momentum.

Why is the speed of recoil small?

From the conservation of momentum, the momentum of the rifle is equal to the momentum of the bullet. Momentum is given as mv. Therefore, the speed of the rifle’s recoil is small because it has much more mass than the bullet. This helps in keeping the momenta of the rifle and the bullet equal.

Why do padded dashboards make automobiles safer?

Padded dashboards make automobiles safer because they increase the time taken to decrease the momentum of an impacting body to zero, which decreases the impact. Thus, the force acting on the padded dashboards is small.

Which has more momentum a heavy truck?

Momentum is the mass of an object multiplied by its velocity. A moving truck has more momentum than a car moving at the same speed because the truck has more mass.

Which has more momentum a huge truck that is not moving or a small toy cart that is moving Brainly?

Answer: Momentum is owned by a moving object. A large truck that doesn’t move means it’s at rest, so the speed is 0.

Which of the following is a way to decrease momentum?

Decreasing either mass or velocity will decrease momentum.
