Question

an object is starting from rest and travels witha. uniform acceleration 2 m/s for 1 minute its final velocity is ​

Answer 1

Correct Question :

An object is starting from rest and travels witha. uniform acceleration 2 m/s² for 1 minute its final velocity is.

Given :

• Initial velocity, u = 0 m/s (starting from rest)
• Time, t = 1 minutes
• Acceleration, a = 2 m/s²

To find :

• Final velocity, v

According to the question,

Note : We have to convert 1 minute into seconds.

• 1 minute = 60 seconds

★ By using First equation of motion,

➞ v = u + at

Where,

• v = Final velocity
• u =Initial velocity
• a = Acceleration
• t = Time

➞ Substituting the values,

➞ v = 0 + 2 × 60

➞ v = 0 + 120

➞ v = 120

• So, the final velocity is 120 m/s.

More formulas :

Newton's first equation of motion :

• v = u + at

Newton's second equation of motion :

• s = ut + ½ at²

Newton's third equation of motion :

• v² = u² + 2as

Answer 2

Answer:

Given :-

• An object is starting from rest and travels with uniform acceleration of 2 m/s² for 1 minutes.

To Find :-

• What is the final velocity (v).

Formula Used :-

To find final velocity (v) we know that,

★ v = u + at ★

where,

• v = Final velocity
• u = Initial velocity
• a = Acceleration
• t = Time

Solution :-

Given :-

• Initial velocity = 0 m/s
• Acceleration = 2 m/s²
• Time = 1 minutes = 60 seconds

According to the question by using the formula we get,

⇒ v = 0 + 2(60)

⇒ v = 0 + 2 × 60

⇒ v = 0 + 120

➠ v = 120 m/s

∴ The final velocity of an object is 120 m/s .
