1. A train starting from rest and moving with a uniform acceleration attains a speed of 36km/h in 10 minutes. Find its acceleration.
2.A bus running at a speed of 18 km/h in 2.5 seconds by applying brakes. Calculate the retardation produced.
3. A motorcycle moving with a speed of 5 m/s is subjected to an acceleration of 0.2 m/s2 for 5 min, calculate the speed acquired and the distance travelled in this time.
please explain me this elaborately with answers and formulas used... as physics is too complicated! =(
