A train 500 m long is moving on a straight track with a speed of 80.3 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 15.2 km/h. Assuming constant acceleration, determine how long the train blocked the crossing. Disregard the width of the crossing.

Please answer all question parts: A Lockheed Martin F-35 Lightning II jet takes off from an aircraft carrier with a runway length of 97 m and a takeoff speed 72 m/s at the end of the runway. Jets are catapulted into airspace from the deck of an aircraft carrier with two sources of propulsion: the jet propulsion and the catapult. At the point of leaving the deck of the aircraft carrier, the F-35's acceleration decreases to a constant acceleration of 4.3 m/s2 at 33° with respect to the horizontal. (Assume that the F-35's initial direction along the deck of the aircraft carrier is the +x-direction and that the +y-direction is up.) (a) What is the initial acceleration (in m/s2) of the F-35 on the deck of the aircraft carrier to make it airborne? (Enter the magnitude.) (b) Write the position (in m) and velocity (in m/s) of the F-35 in unit vector notation from the point it leaves the deck of the aircraft carrier. (Use the following as necessary: t.) (c) At what altitude (in m) is…
An automobile travels on a straight road for 37 km at 45 km/h. It then continues in the same direction for another 37 km at 90 km/h. (a) What is the average velocity of the car during this 74 km trip? (Assume that it moves in the positive x direction.) (b) What is the average speed?
For a standard production car, the highest road-tested acceleration ever reported occurred in 1993, when a Ford RS200 Evolution went from zero to 26.8 m/s (60 mi/h) in 2.782 s. Find the magnitude of the car's acceleration.
A train 400 m long is moving on a straight track with a speed of 84.8 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 16.2 km/h. Assuming constant acceleration, determine how long the train blocked the crossing. Disregard the width of the crossing.
A person takes a trip, driving with a constant speed of 95.5 km/h, except for a 22.0-min rest stop. If the person's average speed is 70.8 km/h, find the following. (a) How much time is spent on the trip? (b) How far does the person travel? km
External stimuli are communicated to the brain by means of electrical signals propagating along nerve cells at a speed of approximately 25 m/s. Similarly, electrical messages are sent at the same speed from the brain along nerve cells to the muscles. Reflex actions are controlled by a relatively simple nerve circuit from a muscle to the spine and back to the muscle. Estimate the reflex time for a stimulus at the knee. (Assume that the signal resulting from the stimulus must travel a distance Δs = 1 m.)
A train 450 m long is moving on a straight track with a speed of 83.9 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 17.1 km/h. Assuming constant acceleration, determine how long the train blocked the crossing. Disregard the width of the crossing.
Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
In order to qualify for the final racing event, a race car must achieve an average speed of 255km/hr on a track with a total length of 1.60*10^3m. If a particular car covers the first third of the track at an average speed of 232km/hr, what minimum average speed must it have in the remaining two thirds of the event in order to qualify?
