A train travels from Station A to Station B which is 4 km away. Departing Station A, it moves at a constant acceleration reaching its cruising speed in 40s which it maintains for 3 minutes. It then decelerates constantly for 80s, coming to a complete stop at Station B. Determine: [a] The cruising speed of the train, in km/hr. [b] The acceleration and deceleration of the train. [c] The distance traveled before the train reaches its cruising speed. \Subject: Dynamics,...

A Train on a straight railway track starts from rest and accelerates at 2.0 m/s2 in 10sec. Then the train covers a distance of 300 m at constant speed for 20 sec until the brakes are applied, stopping the train in a uniform manner in an additional 5.0 s.

A train starts from rest with uniform acceleration of 0.25 m/s^2 and attains a speed of 45 kmph which subsequently remains constant.

An automobile moves on a circular track of radius 1.04 km. It starts from rest from the point (x, y) = (1.04 km, 0 km) and moves counterclockwise with a steady tangential acceleration such that it returns to the starting point with a speed of 29.2 m/s after one lap. (The origin of the Cartesian coordinate system is at the center of the circular track.) What are the car's position and velocity vectors when it is one-sixth of the way...

A spacecraft starts from rest, and makes a journey to a destination 248000 km from its starting point. It does so by accelerating at a constant rate of 15.27 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 15.27 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?
