What is the momentum of a body at rest if its mass is 30kg?

A body of mass 30kg has a momentum of 150kg m//s.

How do you find the momentum of a falling object?

The momentum of a moving object can be determined by multiplying the object’s mass by its velocity. Like velocity, acceleration, and force, momentum is described by both a direction and a strength.

How do you calculate the momentum of an object?

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v).

What is the momentum of a body of mass 10kg if the body is at rest?

The momentum of a body of mass 10 kg is 30 kg m/s.

What is the momentum of a body of mass 10 kg if the body at rest?

Explanation: Answer: Therefore, the momentum of a body of mass kg if the body is at rest is zero.

What is the formula P MV?

Linear momentum is defined as the product of a system’s mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object’s mass and also its velocity.

What is the velocity of the 4 kg object at rest?

A 4.0 kg object is moving at 5.0 m/s NORTH. It strikes a 6.0 kg object at rest. The objects have an elastic collision and move is the NORTH or SOUTH direction. What is the velocity of the 6.0-kg object after the collision?

What is the speed of the 15000-kg car during the collision?

A railroad freight car, mass 15,000-kg, is allowed to coast along a level track at a speed of 2.0 m/s. It collides and couples with a 50,000-kg loaded second car, initially at rest and with brakes released. What percentage of the initial kinetic energy of the 15,000-kg car is preserved in the two-coupled cars after collision?

How do you find the force due to gravity in free fall?

Now you need to find the free fall time and force due to gravity. Newton’s second law tells us that F = m a. Due to the equivalence principle, we can say that F = m g (where g is the acceleration due to gravity.) So, the force applied is m g.

How do you calculate the force applied when an object falls?

Newton’s second law tells us that F = m a. Due to the equivalence principle, we can say that F = m g (where g is the acceleration due to gravity.) So, the force applied is m g. Now, we need to calculate the time the object takes to fall.
