Answer 1

❒ Given:

A bus decreases its speed from 80m/sec to 60m/sec in 5 hour. Find the acceleration.

❍ To Find:

${▪︎Acceleration}$

♣ Step-by-step Answer with Explanation:

We have,

Initial velocity, u = 80 m/s

Final velocity, v = 60 m/s

Time, t = 5 hour or

$5×60×60 = 1800 \: \: second$

Acceleration, a= ?

Now, we know that formula to find acceleration is:

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

After applying this formula, we have,

$:⟹\frac{60 - 80}{5}$

$:⟹ \frac{ - 20}{5}$

$:⟹ - 4$

➲Final Answer:

⌑ Acceleration = -4
