Question

A body is moving with a uniform acceleration of 10m/s² . If its initial velocity is 0 . Calculate the displacement after 5 seconds​

Answer 1

Given

☞ Initial velocity = 0

☞ Acceleration = 10 m/s²

☞ Time = 5 seconds.

To find

☞ Displacement of body

Solution

We have ;

⟼ Initial velocity (u) = 0

⟼ Acceleration (a) = 10 m/s²

⟼ Time (t) = 5 s

Now using 2nd equation of motion :-

⟼ s = ut + ½ × at²

Now substuting values,

⟼ s = 0 × 5 + ½ × 10 × 5²

⟼ s = 0 + 5 × 25

⟼ s = 0 + 125

⟼ s = 125 m

∴ Displacement of body = 125 m [Answer]

Answer 2

Answer:

125m

125mExplanation:

125mExplanation:u=0

125mExplanation:u=0a=10m/s2

125mExplanation:u=0a=10m/s2t=5sec

By using 1st equation

V=u+at

=0+10*5

=50m/s

By using 3rd equation

$v ^{2} - u ^{2} = 2as$

$(50) ^{2} -(0) ^{2} = 2 \times 10 \times s$

$2500 - 0 = 20s$

$s = 2500 \div 20$

So displacement=125m
