How much force is required to accelerate a 2 kg mass at 3m s? Force (F)= Mass (m)× Acceleration (a). ∴F=ma. ∴F=(2kg)×(3ms2). ∴F=6kgms2=6 Newton. What is a body of mass 2 kg moving with acceleration 3 meters per second square? Therefore, change in momentum in one second is 6 kgm/s2. How much net force is […]

What is a body of mass 2kg moves with an acceleration 3ms? Answer: the force acting on the body with a mass of 2 kg and an acceleration of 3 m/s² is 6 Newtons (N). Where: F is the force in Newtons (N). What is a 2 kg object moving at a speed of 3.0

What is the potential energy of a 2kg block moving along the x-axis? The potential energy of the particle of mass 2 kg moving along the x-axis is given by U(x)=4x^2-2x^3 (where U is in joules and x is in meters). What is the position X of a particle of mass 2kg moving along the

Is it correct to say that if no net impulse is exerted on a system then no change in the momentum of the system will occur Newton’s second law of motion states that if no net force is exerted on a system, no acceleration is possible. Does it follow that no change in momentum can

What is the kinetic energy of the car in joules? mass (kg) kinetic energy (J) car at 30 mph 1,500 135,000 car at 60 mph 1,500 540,000 car at 90 mph 1,500 1,214,000 small meteorite 1 200,000,000 Which of the following is an example of kinetic energy? A person walking, a soaring baseball, a crumb

At what speed will the car’s kinetic energy be half of what it is in part BB? When the speed of a car is halved what happens to its kinetic energy? If the speed is halved (keeping the mass same), the kinetic energy decreases, it becomes one-fourth (since kinetic energy is proportional to the square

Are bumper cars elastic or inelastic? Bumper : ​If the bumpers are “bouncy” then the collision is said to be elastic – the two cars bounce off each other. They might exchange kinetic energy and momentum, but the total amount of kinetic energy and momentum remains constant through the collision. What is the physics behind

What is the position of an object moving in a straight line is given as a function? The position function of an object moving along a straight line is given by s = f(t). When the speed of an object moving along a straight line is constant its motion is said to be? Uniform motion

How much force does a 3000 pound car traveling 70 mph have? According to Newton’s second law of motion, a 3,000-pound vehicle traveling at 70 miles per hour has approximately 15.8 million pounds of forward-moving force to release in the event of a collision. What is the kinetic energy of a 3000 lb car traveling

Is momentum conserved in an elastic collision? An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. What is the formula for momentum collision? Before the collision, one car
