Question

a bus dexreases its speed from 50m/s to 20 m/s in 5 second.retardation of the bus is​

Answer 1

Question:-

a bus decreases its speed from 50m/s to 20 m/s in 5 second.retardation of the bus is________.

Answer:-

• The retardation is 6 m/s²

To find:-

• Retardation of bus

Solution:-

• Retardation is negative acceleration. (a)
• Initial velocity (u) = 50 m/s
• Final velocity (v) = 20 m/s

$\red{ \boxed{ \huge{ \green{a = \frac{v - u}{t} }}}}$

$\large{ : \implies \: a = \frac{20 - 50}{5} }$

$\large{ : \implies \: a = \frac{ - 30}{5} }$

$\large{ : \implies \: a = - 6 \: {ms}^{ - 2} }$

• The retardation is 6 m/s².
