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 kinetic energy is a vector with xand y-components?

    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
