Question

3. A car’s velocity changes from 0
m/s to 30 m/s in 10 seconds.
Calculate acceleration.

Final speed =

Initial speed =

Time =

Remember (final speed – initial speed) ÷ time is
acceleration.

This car is_________________?

Answer 1

Explanation:

Initial velocity (u) =0m/s

Final velocity (v) =30m/s

Time taken (t) =10sec

Acceleration =(v-u) /t

= 30-0/10 = 30/10

= 3m/s^2

Answer 2

Answer:

Acceleration = 3m/s²

Explanation:

Given Information -

• Initial velocity (u) =0m/s
• Final velocity (v) = 30m/s
• Time(t) = 10 seconds.

ㅤ

To Find -

• Acceleration (a)

ㅤ

Answer-

To find the acceleration, we'll follow the below given formula, replace the values with it and find our answer.

ㅤ

• $\tt\red{acceleration=\frac{v-u}{time}}$

ㅤ

$\frac{30 - 0}{10} \\ \\ = 3$

Acceleration is 3m/s².
