5.What is the average acceleration of an object that is moving at 5 m/s, and 3 seconds later is traveling ? *
Answers
Given data :
- Initial velocity, u = 0
- Final velocity, v = 5 m/s
- Time taken, t = 3 sec
To find : The average acceleration of an object ?
Solution : Now, we use kinematical equation, {to find out the average acceleration of an object}
➜ v = u + a * t
Where,
- a is acceleration
➜ 5 = 0 + a * 3
➜ 5 = 3a
➜ a = 5/3 m/s² or 1.6667 m/s²
Answer : Hence the average acceleration of an object is 5/3 m/s² or 1.6667 m/s².
{More info :
➜ s = ut + ½ at²
where,
- s is displacement
➜ s = 0 * 3 + ½ * 5/3 * 3²
➜ s = 0 + 5/6 * 9
➜ s = 40/6
➜ s = 20/3 m or 6.6667 m}
Kinematical equations :
- v = u + at
- s = {(u + v)/2}*t
- s = ut + ½ at²
- s = vt - ½ at²
- v² = u² + 2as
{Where, u is the initial velocity of the particle, v is the velocity after time t, s is the displacement of the particle in time t and a is the uniform acceleration of the particle.}
