Question

A drag racer starts from rest and accelerates at 5.2 m/s. How far will he travel in 7.0 seconds?

Answer 1

required distance=127.4 metre

Step-by-step explanation:

given ,accelration=5.2 m/s,time=7 sec

so s=
`0.5*{a}{t^2}`

where a=accelration, t=time,s=distance

s=
`0.5*[5.2][7^2]`

s=127.4 metre
