What is the momentum of a car traveling in a straight line at 20 m sec?
The momentum of a car traveling in a straight line at 20 m/sec is 24,500 kg·m/sec.
What is the expression for the velocity of the system after the collision?
What is the formula of collision? From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ = (m1v1 + m2v2)/m1 + m2.
How does the mass of your car affect its motion?
Weight affects speed down the ramp (the pull of gravity), but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.
What is the momentum of a car with a mass of 1300 kg?
Answer: Momentum of the car is 36400 kg-m/s.
What is the formula for the momentum of a car?
p = m v . p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v).
What is the formula for momentum law of motion?
Every moving object has momentum, and momentum is defined as the product of an object’s mass and its velocity. As an equation, this can be written as p = m v , where p represents the momentum. Since an object’s velocity can change, the momentum of the object can change.
What is the formula for final velocity?
If you know the acceleration rate of the object, you can find the final velocity using the formula vf (final velocity) = vi (initial velocity) + a(t) (acceleration x time).
What is the formula for the total momentum of the system after collision?
The total momentum is the total mass times the velocity of the centre of mass, so the total momentum, before and after, is (2m)(v/2) = mv.
How to calculate velocity?
Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.
What is Newton’s second law called?
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.
What is Newton’s second law example?
Acceleration of the rocket is due to the force applied, known as thrust, and is an example of Newton’s second law of motion. Another example of Newton’s second law is when an object falls from a certain height, the acceleration increases because of the gravitational force.
What is Newton’s second law of pushing a car?
The second law: When a force is applied to a car, the change in motion is proportional to the force divided by the mass of the car. This law is expressed by the famous equation F = ma, where F is a force, m is the mass of the car, and a is the acceleration, or change in motion, of the car.
What does a bus moving along a straight line at 20m s undergo?
The correct Answer is:D Step by step video, text & image solution for A bus moving along a straight line at 20 m/s undergoes an acceleration of 4 m/s^(2).
What is the speed of a moving car is 20 m per second?
⇒72 km h−1.
What acceleration does a body moving along a straight line at 20m s undergo?
A body is moving along a straight line at 20 ms- undergoes an acceleration of 4 ms-2.
What is the momentum of 1000 kg car moving northward at 20 m?
p = mv = (1000kg)(20m/s) = 20000 kg m/s, northward • c.
