Question

A body is moving with velocity of 3 m/s. Find
the distance travelled in 4 second is (1) its
velocity is onstant (II) its acceleration is 2 m/s2
a) 12,20
b) 12,12
C) 12,20
d) None​

Answer 1

(i) When a = 0:-

We know, s = vt

∴ s = (3 m/s)(4 s)

⇒ s = 12 m

(ii) When a = 2 m/s²:-

We know, s = ut + ½ at²

∴ s = (3 m/s)(4 s) + ½(2 m/s²)(4 s)²

⇒ s = 12 m + 16 m

⇒ s = 28 m

So, d) None.
