Question

find the acceleration when initial velocity is 15 metre per second and final velocity is 35 metre per second and the time is 15 second​

Answer 1

Answer :

1.33 (approx) m/s²

=============================

Given :

Initial Velocity (u)  = 15 m/s

Final Velocity (v)  = 35m/s

Time (t)                 = 15 sec

=============================

To Find :

Acceleration

=============================

Lets Solve :

Here, initial velocity, final velocity

and time is given.

We know that,

Acceleration = $\dfrac{Change\:in\:velocity}{Time\:taken}$

means,

$a=\dfrac{v-u}{t}\\\\a=\dfrac{35-15}{15}\\\\a=\dfrac{20}{15}\\\\\therefore a=1.33\:(approx)\:m/s^2$

Answer 2

Given:

• Initial Velocity = 15m/s

• Final Velocity = 35m/s

• Time = 15sec

To Find :

• Acceleration = ?

Solution:

We know Formula of acceleration,

$✓ \: a = \frac{v - u}{t}$

Placing Values,

$⟹ \: a = \frac{35 - 15}{1}$

$⟹a = \frac{\cancel{20}}{\cancel{15}}$

$⟹a = 1.33 \: {m</strong><strong>/</strong><strong>s}^{2}$

⛬ Acceleration is 1.33m/s².
