1. In 1896 in Waco, Texas, William Crush of the "Katy" railroad parked two locomotives at opposite ends of a 6.4 km long track, fired them up, tied their throttles open, and then allowed them to crash head-on at full speed in front of 30000 spectators. Hundreds of people were hurt by flying debris; several were killed... Assuming each locomotive weighed 1.2×10°N and its acceleration along the track was a constant 0.26 m/s, what was the total kinetic energy of the two locomotives just before the collision?

Hello, I have been trying to figure out the answer to these 4 questions and I can’t seem to get them.
In 1896 in Waco, Texas, William Crush of the “Katy" railroad parked two locomotives at opposite ends of a 6.4 km long track, fired them up, tied their throttles open, and then allowed them to crash head-on at full speed in front of 30000 spectators. Hundreds of people were hurt by flying debris; several were killed.. 1. Assuming each locomotive weighed 1.2×10° N and its acceleration along the track was a constant 0.26 m/s?, what was the total kinetic energy of the two locomotives just before the collision? "TRAIN CRASH AT CRUSH. TEXAS: AMERICA'S DEADLIEST PUBLICITY STUNT" 6 p.m. • February 20 • Mayborn Museum Theatre 2. A car with an initial velocity of 36 km/h accelerates at 54 km/h? for 3600 s. By which factor below will the kinetic energy be increased? 3. A 1.5 g bullet takes 2.0 x 103 s to exit the barrel of a gun which is 1.0 m long. How much energy does the bullet have the instant exits the gun? 1.0 m gun barrel A baseball with a mass of 275 g is pitched and reaches the catcher with a speed of 25 m/s. In stopping the ball, the catcher's hand moves back 0.30 m. 4. What is the average stopping force exerted on the baseball?
