Question

A particle travels a distance of 5.00 m in 1.25 seconds, its speed in
m/s' is ?
a) 4 m/s
b) 4.0 m/s
c) 4.00 m/s
d) None of these​

Answer 1

Answer:

4 m/s

Explanation:

Given :

• Distance covered by the object = 5.00 metres

• Time taken by the object to cover a distance of 5 metres = 1.25 seconds

To find :

• Speed of the particle with which it is moving

Speed = distance / time

Speed = 5.00/1.25

Speed = 4 m/s

In the above options (a), (b), (C) are correct as zeroes after a decimal point aren't to be counted

Hence option (a), (b), (C) are correct

✰✰ ANSWER ✰✰

$\longmapsto\tt{Distance\:Travelled=5m}$

$\longmapsto\tt{Time\:Taken=1.25sec}$

$\longmapsto\tt{Speed=?}$

➥Using Formula : -

$\longmapsto\tt{\small{\boxed{\bold{\bold{\orange{\sf{Speed=\dfrac{Distance}{Time}}}}}}}}$

➥Putting Values : -

$\longmapsto\tt{Speed=\dfrac{5\times{100}}{125}}$

$\red\longmapsto\:\large\underline{\boxed{\bf\green{Speed}\orange{=}\purple{4m/s}}}$

☛So , Options a,b and c are correct because zero after point is not counted...
