2. A scooterist moves with uniform accelera ion of2 m/s² for 5 s. Find his final velocity if his presentvelocity is 18 km/h.​

Answer»

Solution :-

Given :-

Initial Velocity = 18 km/h or

= 18 × 5/18

= 5 m/s

Acceleration = 2 m/s²

TIME = 5 sec

Now we have to Solve this :-

We have GOT the initial velocity ,time and acceleration

So we can use the motion equation

v = u + at

→ v = 5 + 2(5)

→ v = 5 + 10

→ v = 15 m/s

Now EITHER velocity = 15 m/s or

= 15 × 18/5

= 54 km/h

So velocity

\Huge{\boxed{\sf{ = 15 \: m/s}}}

Or

\Huge{\boxed{\sf{ = 54 \: km/h}}}
