Question

the velocity of motorcycle increases by the acceleration of 2ms square and becomes 20 meter per second in 5 seconds find the initial velocity of the car​

Answer 1

Answer :

Acceleration = 2m/s²

Final velocity after 5s = 20m/s

We have to find initial velocity of car$.$

◈ What is acceleration !

Acceleration is defined as the rate of change of velocity.

It's a vector quantity having both magnitide as well as direction.

• Formula : a = (v - u) / t

Let's calculate ☃

⇒ a = (v - u) / t

⇒ 2 = (20 - u) / 5

⇒ 10 = 20 - u

⇒ u = 20 - 10

⇒ u = 2m/s

Answer 2

Answer:

10 m/s

Explanation:

we know that accleration is rate of change of velocity.

accleration =(final velocity-initial velocity)/time

(20-x)/5=2

(20-x)=10

x=10m/s
