Question

$\huge\rm\underline\purple{Question:-}$
A train starts from rest and accelerate uniformly at the rate of 5 m/s2 for 5 sec. Calculate the velocity of train in 5 sec.​

Answer 1

$\large\underbrace{\purple{SOLUTION:-}}$

GIVEN :-

• A train starts from rest and accelerate uniformly at the rate of “5m/s²” for ‘5sec’ .

☞ That means,

• u (initial Velocity) = 0 m/s
• a (acceleration) = 5 m/s²
• t (time) = 5 second

FORMULA :-

✪ when a body moves with uniform acceleration or constant acceleration, then the Equation of Motion is,

$\checkmark\:\bf\underline{\blue{\boxed{v\:=\:u\:+\:at\:}}}$

→ where,

• v = final velocity
• u = initial Velocity
• a = acceleration
• t = time

TO FIND :-

• v (final velocity) of train in 5 second

CALCULATION :-

$\rm{v\:=\:0\:+\:5\times{5}\:}$

$\rm{\red{\boxed{\implies\:v\:=\:25\:m/s\:}}}$
