Question

5. A body has an acceleration of -2.5 m/s2. What is its retardation?
please help me
please solve the problem
and solve with full solution ​

Answer 1

Given :

• A body has an acceleration of -2.5 m/s²

To Find :

• The retardation of the body.

Solution :

Given that, the acceleration of a body is - 2.5 m/s². So the retardation will be opposite to - 2.5 m/s².

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• $\bigg\lgroup\sf ( - ) \: \rightarrow \: ( + ) \bigg\rgroup$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\dashrightarrow \: \: \bf Retardation = - 2.5 \: m/s^2 \ \bigg( ( - ve) \rightarrow \: (+ ve) \bigg)$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\dashrightarrow \: \: \underline{ \boxed{ \bf{Retardation = 2 \: m/s^2}}} \blue{ \bigstar}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\therefore \: \underline{ \sf{Retardation \: is \: = \bf{2 \: m/s^2}}}$

⠀⠀⠀⠀______________

Additional Information :

• Acceleration is the rate of change of velocity of an object.
• Negative acceleration is known as retardation.

$\red{\dag}$ $\underline{\boxed{\sf{Acceleration = \dfrac{v - u}{t}}}} \blue{\star}$

• v = final velocity
• u = initial velocity
• t = time taken

Answer 2

To Find:

The retardation of the body

Step-by-step-explanation:

Given that, the acceleration of a body is - 2.5 m/s$^{2}$ So the retardation will be opposite to - 2.5 m/s$^{2}$

(−)→(+)

Retardation=−2.5m/s $^{2}$ ((−ve)→(+ve))

Retardation is $2 \: m/s ^{2}$
