Question

In 5 Second if velocity of car increase from 10m/s to 20m/s find acceleration (step by step) ?​

Answer 1

Answer:

Equation of Kinematics: These are the various relations between u, v, a, t and s for the particle moving with uniform acceleration where the notations are used as:

Equations of motion can be written as

V = U + at

V2 =U2+ 2as

Where, U = Initial velocity, V = Final velocity, g= Acceleration, t = time, and h= height/Distance covered

Where u = Initial velocity of the particle at time t = 0 sec

v = Final velocity at time t sec

a = Acceleration of the particle

s = Distance travelled in time t sec

CALCULATION:

Given - Initial velocity (U) = 10 m/s, Final velocity (V) = 20 m/s and time (t) = 5 sec

Acceleration can be calculated by using equations of motion

⇒V = U + at

Answer 2

Answer:

2 m/s

Explanation:

Given :-

Initial velocity = 10 m/s

Final velocity = 20 m/s

Time taken = 5 sec

To find :-

Acceleration

Solution :-

Acceleration = Change in velocity/Time taken

• 20 - 10/5
• 10/5
• 2

∴ Acceleration is 2 m/s.
