Question

A train starts from rest and Acceleration uniformly at the rate 5m/s2 for 5 sec

Answer 1

★★Question;-

✓✓A train starts from rest and Acceleration uniformly at the rate 5m/s2 for 5 sec .calculate the velocity of train in 5 seconds.

★★Given;-

• $u= 0$

• $a =5m/{s}^{2}$

• $t= 5 sec$

★★Answer;-

First we have to apply the formula of velocity

The formula is:-

$V= u+at$

• V= final velocity

• U = initial velocity

• a=acceleration

• t= time

so,

According to question,

$V=0+5×5$

$V=25$

$\boxed{\boxed{{V=25m/s}}}$✓✓

Answer 2

Correct Question :-

A train starts from Rest and accelerate uniformly at the rate of 5m/s^2 for 5 sec. Calculate the final velocity of Train.?

Given

➜ Initial velocity (u)=0m/s

➜ Acceleration (a)=5m/s^2

➜ Time taken (t)=5sec.

To Find

➜ Final Velocity of Train ???

Solution

•By first equation of motion •

$v = u + at \\ \\ v = 0 + 5 \times 5 \\ \\ v = 25m \: per \: second$

•Hence the required answer is 25m/s .•
