timofeeve [1]
Initia Velocity(u) :- 15m/s

Acceleration(a) :- 4m/s2

Time Taken(t) :- 50 Seconds

{ok a formula is there —->>> s = ut + 1/2 at2(it is ‘t’ square)….. now we will write like this and yeah don’t write this}

We Know,

s = ut + 1/2 at2

s = (15*50 + 1/2 *4*50*50)m

s= (750 + 5000)m

s = 5750 m

Therefore distance traveled is 5750 meters.

Hopefully this helps
