Assume that the kinetic energy of a 1000 kg car moving at 125 km/h could be converted entirely into heat.What amount of water could be heated from 16 ∘C to 52 ∘C by the car's energy? Express your answer using two significant figures.
Part A 104-kg truck going 20 km/h? At what speed must a 950-kg subcompact car be moving to have the same kinetic energy as a 3.2 × Express your answer using two significant figures. 困? u= km/h
An empty truck traveling at 10 km/h has kinetic energy. How much kinetic energy does it have when loaded so that its mass and its speed are both doubled?
A truck of mass 9M is moving at a speed v = 15 km/h when it collides head-on with a parked car of mass M. Spring mounted bumpers ensure that the collision is essentially elastic. Find the final velocities of each vehicle. Repeat for the case of the car moving at speed v= 15km/h and colliding with the stationary truck. What fraction of the incident vehicle’s kinetic energy is transferred in each case?
