Answer:
240.8
Step-by-step explanation:
→ Calculate time taken
16:43 - 14:56 = 1 hour and 47 minutes
→ Write the speed formula and make distance the subject
Speed = Distance ÷ Time ⇔ Distance = Speed × Time
→ Convert 1 hour and 47 minutes into decimal format
1.78333333 or
→ Substitute values into formula
135 × = 240.75
Answer:
The recoil velocity of the gun is and is pointing in opposite direction to the velocity of the bullet.
Step-by-step explanation:
Use conservation of linear momentum, which states that the momentum of the bullet (product of the bullet's mass times its speed) should equal in absolute value the momentum of the recoiling gun (its mass times its recoil velocity).
We also write the mass of the bullet in the same units as the mass of the gun (for example kilograms). Mass of the bullet = 0.010 kg
In mathematical terms, we have:
