Answer:
d)
Explanation:
Newton's 3rd Law tells us that for every action we will have a reaction equal in magnitude and opposite in direction. In a collision between obects A and B this means that the force on A applied by B will be equal in magnitude than the force on B applied by A, which leaves d as the true answer and the rest as false.
Answer:
The answer is A
Explanation:
From a logical standpoint, the car would get more damage than the truck because the truck is heavier and can withstand more weight. 20 tons converted to lbs is 40 000, while the car only weighs for 1 500 lbs. 1 500 lbs is 3.75% of 40 000.
(Heres the math)
Formula to be used = F = m x a
Let's say that the car is a Scion IQ which weighs around 1 800~1 900 lbs, The Scion IQ's max speed is 125 km/h or 78 mph. It can go from 0 km/h to 100 km/h in 14 seconds. This gives us an acceleration of 1.984 m/s².
F = m x a
F = 1 800 lbs x 1.984 m/s²
F = 1619.87 N (Approximate)
Do the same for the truck. Let's say its a fire truck that weighs around 41 000 lbs and can go 68 mph. The NFPA said that fire trucks should be able to accelerate from 0 mph to 50 mph in 25 seconds or less, so we will use that. Lets also say that the fire truck can accelerate to 50 in 24 seconds, this gives us an acceleration of 0.9313 m/s².
F = m x a
F = 41 000 lbs x 0.9313 m/s²
F = 17319.65 N (Approximate)
Final Conclusion
17319.65 N > 1619.87 N
