Question

A buss decreses its speed from 20m/s to10m/s in 5s find its acceleration​

Answer 1

Answer:

Answer. Therefore the acceleration of the bus is -2 m/s. Since the acceleration is negative, this is case known as retardation.

Answer 2

Given :

• Initial Velocity = 20m/s
• Final Velocity = 10m/s
• Time Taken = 5 sec.

To Find :

• Acceleration of the bus.

Solution :

For Acceleration :

Using Formula :

$\longmapsto\tt\boxed{Acceleration=\dfrac{v-u}{t}}$

Putting Values :

$\longmapsto\tt{\dfrac{10-20}{5}}$

$\longmapsto\tt{\cancel\dfrac{-10}{5}}$

$\longmapsto\tt\bold{-2{m/s}^{2}}$

So , The Acceleration of the bus is -2m/s²...

Acceleration :

The Rate of change of velocity of an object is known as Acceleration . Acceleration is measured in m/s².

Formula for Acceleration :

$\longmapsto\tt\boxed{a=\dfrac{v-u}{t}}$

Here :

• a = Acceleration
• v = Final Velocity
• u = Initial Velocity
• t = Time Taken
