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

Answer 1

Answer: (C)

30 m

Answer 2

The correct answer is (C) : 30 m
$\frac{1}{2} at² = 10 m$
$\frac{1}{2} a(2t)² = 40 m$
⇒ Distance travelled in next t s
= 40 – 10 = 30 m
