<h3>
Answer:</h3>
375 N
<h3>
Explanation:</h3>
Topic tested: Newton's Law of motion
The question is testing on the application of Newton's second Law of motion.
We are given;
- Mass of the football = 5 Kg
- Initial velocity of the football, Vf = 15 m/s
- Time taken to bring the ball to rest = 0.2 s
- Final velocity, Vo = 0 m/s ( since the ball went to rest)
We are required to determine the force exerted to bring it to rest.
- According to the Newton's second law of motion the resultant force and rate of change in momentum are directly proportion.
Thus;
Force = 375 N
Hence, the force exerted on the ball by the receiver was 375 N
Answer:
Livestock is commonly defined as domesticated animals raised in an agricultural setting to produce labor and commodities such as meat, eggs, milk, fur, leather, and wool. In particular, livestock, especially beef, dairy and sheep stocks, have out-sized influence on greenhouse gas emissions from agriculture
Explanation:
Hope You Understand. Sorry It's Too Late LOL
Formula to calculate speed:
Speed=Distance/Time
Distance: 24 m
Time: 3 sec
24/3=8
So the correct answer is 8 m/s
Answer:
15 m/s to the right
Explanation:
Let's say right is positive and left is negative.
Momentum is conserved:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(6.0 kg) (25.0 m/s) + (15 kg) (0 m/s) = (6.0 kg) (-12.5 m/s) + (15 kg) v₂
v₂ = 15 m/s
