Question

u=30m/s ,, v=60m/s ,, t=8s ,, a=??​

Answer 1

Answer:

A=v-u/t

=60-30/8

=30/8

=3.75

Answer 2

Question:-

If u = 30 m/s , v = 60 m/s and t = 8s,

Then find acceleration (a).

Here,

• u is the initial velocity
• v is the final velocity
• t is the time
• a is acceleration

Answer:-

→ Acceleration = 3.75 m/s^{2}

To Find :-

→ Find acceleration.

Formula used:-

Here we use first equation of motion

$\implies \: \bf{ v \: = u \: + at \: }$

Solution:-

Given that,

• Initial velocity (u) = 30 m/s
• Final velocity (v) = 60 m/s
• Time (t) = 8 second
• Acceleration (a) = ?

Now ,

Apply the given formula ,

$\implies \: \bf{ v \: = u \: + at}$

Substitute the given values,

$\implies \: 60 = 30 + a \: \times 8 \\ \\ \implies \: a \times 8 = 30 \\ \\ \implies \: a \: = \frac{30}{8} \\ \\ \implies \: \boxed{a \: = 3.75} \: \frac{m}{ {s}^{2} }$

Therefore,

Acceleration is 3.75 m/s^{2}
