Answer 2

Given:-

★ Initial velocity , u = 15 m/s

★ Final velocity, v = 30 m/s

★ Time, t = 10 sec

To Find :-

★ Acceleration, a = ?

Solution :-

To find acceleration, we need to use first equation of motion.

We know,

$\boxed{\sf v = u +at}$

Where,

v =Final velocity

u = Initial velocity

a =Acceleration

t = Time

Now, put the given values

⟹ 30 = 15 + a × 10

⟹ a =1.5 m/s²

Hence,

acceleration of the bike is = 1.5 m/s²

Know more :-

☞ Force = mass × acceleration

☞ v = u + at

{ 1st equation of motion}

☞ s = ut + ½ at²

{ 2nd equation of motion}

☞ v² = u² + 2as

{ 3rd equation of motion}

☞ Pressure = Force/Area
