Question

What is the acceleration produced in a body of mass 5kg when 7N force is applied on it

Answer 1

Answer:

0.875 m/s²

Explanation:

As per the provided information information in the given question, we have :

• Mass of the body (m) = 5 kg
• Force applied (F) = 7 N

We are asked to calculate acceleration (a).

As we know that,

• Force is the product of mass and acceleration.

➝ F = ma

Substitute the values we have,

➝ 7 N = 5 kg × a

• 1 N = 1 kg m/s²

➝ 7 kg m/s² = 5 kg × a

➝ $\sf \dfrac{7 \; kg\; m/s^2}{5 \; kg}$ = a

➝ 0.875 m/s² = a

∴ Acceleration produced is 0.875 m/s².

Points to remember :

• Acceleration is the rate of change in velocity with time.
• It is vector quantity, that means it requires both magnitude and direction for its description.
• SI unit of acceleration is m/s².
• Negative acceleration is called retardation.

$\red {\bigstar } \; \underline{\boxed{\sf{ a = \dfrac{v-u}{t} }}}$

v denotes final velocity

u denotes initial velocity

a denotes acceleration

t denotes time
