A driver of train travelling at a speed of 15m/s applies brakes and retardsthe train uniformly. The train stops in 5 seconds. Another train B is travelling on aparallel track with a speed of 10m/s. its’ driver applies the brakes and the trainstops in 10 seconds retarding uniformly.

A driver of train travelling at a speed of 15m/s applies brakes and retardsthe train uniformly. The train stops in 5 seconds. Another train B is travelling on aparallel track with a speed of 10m/s. its’ driver applies the brakes and the trainstops in 10 seconds retarding uniformly.(a) Plot speed-time graphs for train A and Train B on the same paper.(b) Calculate graphically which of the trains travelled farther after the brakes wereapplied.

The train gets up to 8 m/s along the same straight track. The driver applies the brakes causing the train to accelerate at –0.5 m/s/s.Determine its speed after 1 second, 2 seconds, and 5 seconds.

The driver of a train moving at a speed v1 sights another train at a distance d ahead of him, moving in the same direction with a slower speed v2. He immediately applies brakes to achieve a constant retardation a. There will be no collision if d is greater than(v1−v2)2a(v21−v22)a(v1−v2)22a(v21−v22)2a

A goods train passes through a station at a steady speed of 10 m s –1 at time t = 0. An expresstrain is at rest at the station. The express train leaves the station with a uniform acceleration of0.5 m s –2 just as the goods train goes past. Both trains move in the same direction on straight,parallel tracks.At which time t does the express train overtake the goods train?A 6 s B 10 s C 20 s D 40 s

In a city, the local shuttle trains start from and arrive at the station at fixed intervals and run at a uniform speed. A boy was walking down the railway track at a certain speed. Every half an hour, a local train overtook him and every 20 minutes, a local train passed him in the opposite direction. Find the time interval between a local train passing a certain point on the railway track and the immediately next local train passing that point in the same direction.
