Question

A car starts from the state of xestIf its velocity becomes 70 km/hr in 6 minutes, i) what is the accordine acceleration of F the car? (ii) what is the the distance cover ded by the car?​

Answer 1

Answer:
`3.5\ km`

Step-by-step explanation:

Given

Car starts from the state of rest and acquires a velocity of
`70\ km/hr` in 6 minutes

Final velocity in m/s is
`v=70\approx 19.44\ m/s`

Using equation of motion

`v=u+at\\\Rightarrow 19.44=0+a(6* 60)\\\Rightarrow a=0.054\ m/s^2`

Distance covered in 360 s

`\Rightarrow v^2-u^2=2as\\\Rightarrow 19.44^2-0=2* 0.054* s\\\Rightarrow s=3500.64\ m\approx 3.5\ km`
