Question

Two billiard balls each of mass 0.06 kg moving in opposite directions with speed 5 ms-1 collide and rebound with same speed. The impulse imparted to each ball due to the other are (A) 0.6 kg ms-1 each, in same directions (B) 0.6 kg ms-1 each, in opposite directions (C) 0.6 kg ms-1 each, in transverse directions (D) 1.2 kg ms-1 on one and zero on other

Impulse on each ball =􏰇 Δ p = 0.06 × 10 = 0.6kgms-1 The two impulses are in opposite direction.

Q. Two billiard balls each of mass $0.06 k g$ moving in opposite directions with speed $5 m s^{- 1}$ collide and rebound with same speed. The impulse imparted to each ball due to the other are

$0.6 k g m s^{- 1}$ each, in same directions

$0.6 k g m s^{- 1}$ each, in opposite directions

$0.6 k g m s^{- 1}$ each, in transverse directions

$1.2 k g m s^{- 1}$ on one and zero on other

Impulse on each ball =􏰇 $Δ p$ = $0.06 \times 10 = 0.6 k g m s^{- 1}$ The two impulses are in opposite direction.

Q. Two billiard balls each of mass 0.06kg moving in opposite directions with speed 5ms−1 collide and rebound with same speed. The impulse imparted to each ball due to the other are

0.6kgms−1 each, in same directions

0.6kgms−1 each, in opposite directions

0.6kgms−1 each, in transverse directions

1.2kgms−1 on one and zero on other
