Question

a train travelling at 20 metre per second square accelerates at 0.5 metre per second square calculate the time interval in which it cover the distance of 825 ​

Answer 1

Answer:

Solutions 

We know that a train travelling at 20 m/s accelerates at 0.5 m/s^2 ( 0.5 meters per second square ) for 30 s. 

We have 

u = 20 m/s

a = 0.5 m/s²

t = 30 sec

Solve (calculations)  

s = ut +(1/2) at^²

 = 20×30 + (1/2)×0.5×(30)^²

 Answer

= 825 m
