Question

5. A car is accelerated at the rate of 5 metre/second?. Find the increase in its velocity in 2 seconds
​

Answer 1

Answer:

After two seconds of accelerating at 5 m/s^2 the car velocity will increase by 10 m/s (this is assuming movement in straight line and acceleration in the same direction)

Hope it helps

Answer 2

$\checkmark$ Given:

A car is accelerated at the rate of 5 m/s² and increase in its velocity in 2 seconds

$\checkmark$ To Find:

The increase in its velocity in 2 seconds

$\checkmark$ Solution:

We know that,

$\red{\bigstar \ \boxed{\rm \Delta v=a \times \Delta t}}$

Here,

• Δ v = change in velocity
• a = acceleration
• Δ t = change in time

According to the question,

We are asked to find the increase in its velocity in 2 seconds

Given that,

A car is accelerated at the rate of 5 m/s² and increase in its velocity in 2 seconds

Hence,

• a = 5 m/s²
• Δ t = 2 seconds

Substituting the values,

We get,

$\blue{\rm \implies \Delta v=(5 \times 2) \ m/s}$

$\green{\rm \implies \Delta v=10 \ m/s}$

Therefore,

$\pink{\rm \star \ Increase \ in \ velocity=10 \ m/s}$
