a In mechanics, the energy of a moving body is called kinetic energy. If an object of mass (kilograms) is moving with a velocity v (meters per second), then the kinetic energy k( joules) is given by the equation ke we model the mass and inputs to a system (moving body) and the energy as output, then obnerve the system for while and deduce the following two rules of inference based on our observations Rule 1: IF x is small...

Two carts mounted on an air track are moving toward one another. Cart 1 has a speed of 0.8 m/s and a mass of 0.53 kg. Cart 2 has a mass of 0.71 kg. (a) If the total momentum of the system is to be zero, what is the initial speed of Cart 2 in meters per second? m/s (b) Does It follow that the kinetic energy of the system is also zero since the momentum of the system is...

A projectile traveling at 100 meters per second is stopped by being shot into an insulated tank containing 400 kilograms of water. Kinetic energy of the projectile is completely converted into thermal energy. If the temperature of the water is raised by 0.05 degree C, what is the mass of the projectile? The specific heat of water is 4.18 Joules per gram per degree C.

We learned in class that the kinetic energy (KE) of an object with mass m moving at velocity v is KE =½ m v^2. Accordingly, the kinetic energy (KE) per unit mass (m) of a body moving at velocity v is KE/m=v^2 /2. What is the asteroid’s kinetic energy per unit mass (J/kg) for an impact at this velocity? State your answer in units of J/kg. velocity is 29.8 km/s

A car of mass 2400 kg collides with a truck of mass 4500 kg at the intersection of horizontal roads. The vehicles stick together and slide immediately after the collision. The x- and y-components of the car’s velocity just before the collision are (36, 0) m/s, respectively, and the same components of the truck’s velocity just before the collision are (-15, 25) m/s. a. calculate the x component of the velocity of the combined car and truck immediately after the...
