Answer 1

Answer:

v = $6cms^{-1}$

Explanation:

u = $0cm s^{-1}$

v = ?

a = $2cms^{-2}$

t = 3s

Applying the formula to calculate acceleration,

$a = \frac{v - u}{t}$

$2 = \frac{v - 0}3$

∴ v = 3 × 2

   v = $6cms^{-1}$

Answer 2

Explanation:

u=o cm

a=20cm

v=?

t=3s

Now,

a= u-v/t

2= u-o\3

2×3= 6

therefore velocity =6
