Question

A small toy starts moving from the position of rest under a constant acceleration. If it travels a distance of 10 m in t s, the distance travelled by the toy in the next t s will be : (A) 10 m (B) 20 m (C) 30 m (D) 40 m

u =0, Say acceleration is a For t s 10=(1/2) at 2 For 2 t s 10+ x =(1/2) a (2 t )2 (10+x/10)=(4/1) x=30 m

Q. A small toy starts moving from the position of rest under a constant acceleration. If it travels a distance of $10 m$ in $t s$ , the distance travelled by the toy in the next $t s$ will be :

10 m

20 m

30 m

40 m

$u = 0,$ Say acceleration is a
For t s $10 = \frac{1}{2}$ at $^{2}$
For $2 t s 10 + x = \frac{1}{2} a (2 t)^{2}$
$\frac{10 + x}{10} = \frac{4}{1}$
$x = 30 m$
