A long train

A train passes a standing man in 6 seconds and a 210 m long platform in 16 seconds. Find the length and the speed of the train.

Final Answer:

a =  126 m
v =  21 m/s

Step-by-step explanation:

t1=6 s t2=16 s p=210 m  v = a / t1 v = t2a+p   a/t1 = (a+p)/t2  t2 a=(a+p) t1 16 a=(a+210) 6  10a=1260  a=101260=126  a=126=126 m
v=t1a=6126=21 m/s
