Question

if an object changes its velocity from 10m/s to 30k/s in 5 seconds what is the acceleration of that object​

Answer 1

Answer:

Answer 2

Given

• Initial velocity (u) = 10m/s
• Final velocity (v) = 30m/s
• time taken (t) = 5s

Find out

• Acceleration of an object (a)

Solution

★According to first equation of motion

➟ v = u + at

➟ 30 = 10 + a × 5

➟ 30 - 10 = 5a

➟ 20 = 5a

➟ a = 20/5

➟ a = 4 m/s²

Additional Information

• s = ut + ½ at² {2nd equation of motion}

• v² = u² + 2as {3rd equation of motion}

• Acceleration → The rate of change in velocity.
