Question

a train cross the 500 m platform in 4 sec at the speed of 54 km/h.find the acceleration and the final velocity​

Answer 1

Answer:

Initial velocity = 15m/s

Distance travelled =500m

Time taken =4s

S=ut+1/2at^2

500=15×4+1/2×a×16

500=60+8a

8a= 440

a= 55m/s

Final velocity= u+at

= 15+55×4

= 235m/s
