Question

Two plastic projectiles have the same mass M and speed V when they hit a glass window pane at a right angle. The interaction between both projectiles and the glass pane takes time T. Projectile A bounces off of the window (in the opposite direction) with the same speed V it had at the beginning. Projectile B sticks to the window pane and stops. Describe the likely damage to the glass pane by selecting all the true statements below.

0/1 pts Question 1 Two plastic projectiles have the same mass M and speed V when they hit a glass window pane at a right angle. The interaction between both projectiles and the glass pane takes time T. Projectile A bounces off of the window (in the opposite direction) with the same speed Vit had at the beginning. Projectile B sticks to the window pane and stops. Describe the likely damage to the glass pane by selecting all the true statements below. Projectile B has the greater likelihood of breaking the glass since its final momentum is smaller Projectiles A & B have the same likelihood of breaking the glass since they have the same initial momentum Projectile A has the greater likelihood of breaking the glass since its momentum change is larger Projectile A has the greater likelihood of breaking the glass since its momentum change is smaller

Explanation / Answer

Correct option:3

Its because momentum change of A is twice as large as B.So the Projectile A transmits a larger momentum to glass pane thus increasing its chances of breakage.
