Constants Part A A 75-m-long train begins uniform acceleration from rest. The front of the train has a speed of 18 m/s when it passes a railway worker who is standing 145 m from where the front of the train started (see the figure below). Figure 1) What will be the speed of the last car as it passes the worker Express your answer to two significant figures and include the appropriate units.

The Great Train Robbery (1903) What is the story of this film? What happens? Is the film hard to follow? How is the film different from modern films? How is watching a movie without dialogue unique? What do you lose? What do you gain? Did you notice any interesting technical elements in this film? can someone help me with this please. i have to submit in 2 days. thanks.
A 75-m-long train begins uniform acceleration from rest. The front of the train has a speed of 18 m/s when it passes a railway worker who is standing 200 m from where the front of the train started. What will be the speed of the last car as it passes the worker?
What happens to the acceleration and velocity of an Apache helicopter when it fires a rocket-propelled missile at an enemy tank in front of it? How about the torque exerted by the missile? After launching a missile, will the helicopter's speed be faster, slower, or stay same? Does the pilot have to correct for pitch, yaw, or roll? Provide your reasoning. What parameters would you need to figure those accelerations?
[5] A train of mass mtrain runs along a straight track at speed v. What is the angular momentum of the train relative to a point P that is distance D from the track on the right side (with respect the direction of travel of the train) of the track? [10 pts]
A freight train consists of 5 engines at the front, followed by 20 rail cars. Both the engines and rail cars have the same mass of 695770 kilograms each. Each engine exerts the same force backward on the track to push the train forward. The total force of friction on the entire train is 836754 N and is evenly distributed among all of the cars and engines. Even with this friction present, the train engines are able to accelerate the...
MoneyPenny watches James Bond on a 10m high bridge as a 9.5 foot high train runs underneath it at 12 m/s to her right. If Bond runs to the right and jumps off the bridge at an angle of 30 degrees above the horizontal with as speed of 5 m/s. What is the relative velocity of the train to Bond when he lands on it? (That is just before impact not after impact)
I need help understanding what happens when data changes at the rising edge of a clock, and if it causes a setup or hold violation.
The Josie King story is one of many compelling stories about what happens in healthcare systems when things go wrong and patients experience sentinel events, including irreparable harm or, as in the case of Josie, death. Josie was an eighteen-month-old toddler who had been admitted to Johns Hopkins Hospital for burns she suffered accidentally when her mother was giving her a bath. Josie died from medical errors that could have been avoided. Josie’s mother, Sorrel King, recounts how she tried...
Just solve A and B please!
Velocity addition A train with proper length L' travels with velocity v_t. It takes the conductor in the train the time t_c^' to move through the train from front to back (and the same time to move back again). Things that are in the way will be kicked out of the train at different angles that_t^', but all at the same speed S_o^1 (in the trains frame). What is the speed of the conductor...
