Answer 1

Answer:

Correct Question -

A car initialy at rest starts moving with a constant acceleration of 0.5 ms- 2 and travels distance of 25 m. Find Final Velocity and Distance?

Answer-

GIVEN -

Initial Velocity u = 0

Acceleration = 0.5 m/s²

Distance Travelled = 25 m

To Find

Final Velocity = ?

Tame taken = ?

Velocity =?

$\bold\green{Equation\:of\: Motion}$

v² = u² + 2as

$\implies{v^2 = 0^2 + 2 × 0.5 × 25}$

$\implies{v^2= 25}$

$\implies{v = \sqrt[2]{25}}$

$\boxed{Final\: Velocity\:v\:=\:5ms^-1}$

Time Taken = ?

$\bold\green{Equation\:of\: Motion}$

v = u + at

$\implies{5= 0 + 0.5 × t}$

$\implies{5 = 0.5× t}$

$\implies {t = \frac{5}{0.5}}$

$\fbox{Time\:taken\:=\:10\:s}$
