Question

Acceleration of a body can be calculated using

• A. $a=\frac{F}{m}$
• B. $a=\frac{v-u}{t}$
• C. $a=\frac{P}{m}$
• D. $a=\frac{s}{t}$

Answer 1

Answer: (A), (B)

$a=\frac{v-u}{t}$

Step 1: Given

Acceleration of a body can be calculated using

Step 2: Explanation.

As force $F=ma$
Here, $F=$ force
$m=\text{mass}$
$A=\text{acceleration}$
Hence, we get acceleration, $a=\frac{F}{m}$
Using the equation of motion
$v=u+at$
Here, $v=$ the final velocity
$u=$ initial velocity
$\Rightarrow a=\frac{v-u}{t}$.

Hence, options (A) and (B) are correct.
