The initial velocity of body moving along straight line is 7 mpersecond it has uniform acceleration of 4 m per second square distance covered by the body in 5th second of its motion which formula is correct for it or how can we solv it

Answer»

you can use the CONCEPT like

Distance covered in 6seconds - distance covered in 5second= distance covered in the 5TH SECOND

--> 7+1/2(4×6²) - [7 +1/2(4×5²)] = 22 m
