In travelling a distance of 0.5m, an object gained 200 Joules of kinetic energy. What work was done on the object, assuming no frictional forces acted? What was the average forces acting on the object? If a force of 600N had acted over the same distance, what would have been the gain in kinetic energy?
1. How much kinetic energy does an object of mass m traveling with a velocity vx in the x-direction have? 2. How much kinetic energy does an object of mass m traveling with a velocity ~v = vx ˆi + vy ˆj have? 3. Since the pythagorean theorem states that v ^2 = v ^2 x + v ^2 y , we can write the kinetic energy as K = 1/2mv^2 x + 1/2mv^2 y . Does this mean that...
An 4.7-kg object moving at 12.2 m/s catches up and collides with an 22.3-kg object moving at 2.1 m/s in the same direction. After the collision the 4.7-kg object is observed to be moving in the opposite direction with the speed of 2.6 m/s. How much kinetic energy was lost in this system?
Q) What is the kinetic energy, in joules, of a molecule of oxygen moving at a speed of 255 m/s(use the appropriate prefix to avoid exponential notation) a) The equation for kinetic energy is ½mv2, and is in units of joules. What are the component units for joules in terms of mass and velocity? kg m^2/s^2 b) From the previous part, we know that the mass needs to be in units of kg. What is the mass of an oxygen...

One way to measure the amount of energy that a moving object (auch as a car) possesses is by finding its Kinetic Energy. The Kinetic Energy (Es, measured in Joules) f am object depends on the objects mass m measured in kg) and velocity (v, measured in meters per second), and can be written as - What is the Kinetic Enerzy of an object with a mass of 1,700 kilograms that is traveling at 30 meters per second? Joules Points...
