Question

A car moves with a speed of 50 ms-^1 and covers 100m distance.find out the time tanken to cover this distance.(2 s,20 s,50 s)

Answer 1

Given :

Speed of car = 50m/s

Distance covered by car = 100m

To Find :

Time taken by car to cover this distance.

Solution :

■ Speed : Speed is measured as the ratio of distance travelled to the time taken.

$\bigstar\:\underline{\boxed{\tt{\orange{Speed=\dfrac{Distance}{Time}}}}}$

• It is a scalar quantity having only magnitude.
• It can't be negative or zero.
• SI unit : m/s

By substituting the given values;

$\dashrightarrow\tt\:Speed=\dfrac{Distance}{Time}$

$\dashrightarrow\tt\:50=\dfrac{100}{t}$

$\dashrightarrow\tt\:t=\dfrac{100}{50}$

$\dashrightarrow\:\underline{\boxed{\bf{\gray{t=2\:second}}}}$

■ Additional Information :

• Velocity is defined as the ratio of distaplacement to the time. It is a vector quantity having both magnitude as well as direction.
• Acceleration is defined as the rate of change of velocity. It is also a vector quantity.
