Question

A scooter travelling at 10 m/s speed up to 20 m/s in 4 sec. Find the acceleration of scooter.???​

Answer 1

Answer:

u=10m/s

v=20m/s

t=4s

a=?

v=u+at

20=10+a4

20-10=4a

10/4=a

a=2.5m/s2

Explanation:

Answer 2

Given:

• Initial speed (u) = 10m/s
• Final Speed (v) = 20m/s
• Time (t) = 4 sec

To Find:

• Acceleration of scooter?

Formula Used:

$\\ {\boxed{\sf\pink{a = \dfrac{ \Delta v }{ \Delta t} \: \: \: or \: \: \: a = \dfrac{v-u}{t} } }}$

Solution:

$\implies {\sf{a = \dfrac{ \Delta v }{ \Delta t} }} \\ \\ \implies{\sf{ a = \dfrac{ 20 - 10}{4} }} \\ \\ \implies{\sf { a = \cancel{ \dfrac{10}{4} }}} \\ \\ \implies{\sf{ a = 2.5 \: m/s^2} }$

Therefore:

The acceleration of scooter will be 2.5 m/s².
