Answer:
Explanation:
Applying conservation of momentum
mA v0 + 0 = mA x 12v0 + mB x 92v0
11 mA = - 92mB .
mA / mB = 92 / 11
mA : mB = 92 : 11.
Answer:
0.4 m/s²
Explanation:
average acceleration = (final velocity - initial velocity)/ time elapsed
average acceleration = (6 - 4)/5
average acceleration = 2/5
average acceleration = 0.4 meters/seconds squared or 0.4m/s²
The answer given by E2020 is
"The padding around the goal post increases the time of the collision between the player and the post, which decreases the force exerted to bring the player to a stop"
