An express train passes through a station. It enters with an initial velocity of 22.6 m/s and decelerates at a rate of 0.160 m/s2 as it goes through. The station is 211 m long. (a) How long (in s) is the nose of the train in the station? 9.685 (b) How fast (in m/s) is it going when the nose leaves the station? 21.05 v m/s (c) If the train is 130 m long, when (in s) does the end of the train leave the station? 13.75 (d) What is the velocity (in m/s) of the end of the train as it leaves? (Enter the magnitude.) 20.04 1, m/s

A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 6.65 ✕ 107 km. Radio waves travel at the speed of light (3.00 ✕ 108 m/s). How many seconds does it take for the signal to reach the Earth?

An auto travels at the rate of 25 km/h for 4.0 minutes, then at 50 km/h for 8.0 minutes, and finally at 20 km/h for 2.0 minutes. Find the average speed for the complete trip in m/s?

Two locomotives 70 kilometers apart are travelling on the same track towards each other, Engine A moves at 22 kilometers per hour east and engine B moves at 13 kilometersper hour west. At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till  it was eliminated and c) the average velocity of the fly? how can i find this please

A runner travels I.5 laps around a circular track in a time of 50 s. The diameter of the track is 40 m and its circumference is 126 m. Find (a) the average speed of the runner and (b) the magnitude of the runner's average velocity. Be careful here; average speed depends on the total distance traveled, whereas average velocity depends on the displacement at the end of the particular journey.

A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 7.96 ✕ 107 km. Radio waves travel at the speed of light (3.00 ✕ 108 m/s). How many seconds does it take for the signal to reach the Earth?

A bullet is fired through a board, 0.28 cm thick, with its line of motion perpendicular to the face of the board. If it enters with a speed of 50 m/s and emerges with a speed of 15 m/s, what is the bullet's acceleration in m/s as it

10. A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 25.0 min at 75.0 km/h, 16.0 min at 100.0 km/h, and 40.0 min at 50.0 km/h and spends 30.0 min eating lunch and buying gas. Determine the average speed for the trip. (km/h) Determine the distance between the initial and final cities along the route. (km)

A ball is thrown horizontally from 43 a meter high cliff and lands on the ground 70.6 m from the base of the cliff. What was the ball's initial velocity in m/s?
