A 10000 kg train car A traveling at a speed of 24 m/s strikes an identical car B initially at rest. If the cars lock together as a result of the collision, calculate the amount of the initial kinetic energy is transformed into thermal or other forms of energy.
Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.40×106N , What is the total work done by the two tugboats on the supertanker
Calculate the increase in internal kinetic energy (that is, for the ship and the shell). This energy is less than the energy released by the gun powder-significant heat transfer occurs
The driver of a 1550 kg car, initially traveling at 12.1 m/s, applies the brakes, bringing the car to rest in a distance of 19.5 m. Find the net work done on the car
The minimum distance required to stop a car moving at 34 mi/h is 42 ft. What is the minimum stopping distance for the same car moving at 64.0 mi/h, assuming the same rate of acceleration.
