** please show the work and explain

Answer 1

Answer:

depends on the direction of force applied.

Answer 2

$\huge \bf { _! !☃♡Problem♡☃!_!}$

What will the acceleration be of a 20-kg box if a force of 80 N is applied?

$\huge \bf { _! !☃♡ Solution♡☃!_!}$

Given:

• Mass ( m ) = 20 kg
• Force applied ( F ) = 80 N

To Find:

• acceleration ( a ) = ?

Calculation:

We know that,

• $\red \bigstar$ ${\boxed {\bf {\red { F = ma }}}}$

Where,

☃ F denotes force

☃ m denotes mass

☃ a denotes acceleration

Substituting values:

$\tt { F = ma}$

$\tt { 80 = 20a}$

$\tt { \leadsto a = \dfrac{80}{20} }$

$\tt\purple { a = 4 m/{s }^{2 } }$

Therefore, Acceleration produced was $\tt { 4 m/{s }^{2 } }$

• SI unit of force is Newton.
• Formula: f = ma

____

• Acceleration is the rate of change in velocity with time.
• It is vector quantity.
• SI unit of acceleration is $\tt { m/{s }^{2 } }$
• Formula: a = v-u/t , where v = final velocity, u = intial velocity and t is time.
