#2 What is the kinetic energy of a car weighing 11,688.8 N with a velocity of 50.4 km/h?
A 2000 kg car is moving with a velocity of 50 km/hr. What is its kinetic energy? If the car reduces its speed by half, by what factor is the kinetic energy changed?
What is the kinetic energy in Joules of a 8,699.2 kg truck moving at 63.9 km/hr?
What is the kinetic energy in Joules of a 7,320.4 kg truck moving at 81.1 km/hr?
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

Find the kinetic energy for a 20,000-kg truck moving at 110 km/h
Assume that the kinetic energy of a car with a mass of 1350 kg moving at 150 km/h could be converted entirely into heat. What amount of water could be heated from 25 ∘C to 48 ∘C by the car's energy? Recall that 4.184 J is required to heat 1 g of water by 1∘C
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...
Assume that the kinetic energy of a 1350 kg car moving at 135 km/hr could be converted entirely into heat. What amount of water could be heated from 23 (degrees C) to 45 (degrees C) by the car's energy?
