Answer:
Rocket 2 has highest acceleration.
Explanation:
Net force,
F = mass (m) × acceleration (a)
We have,
m₁ = 4.25 kg and F = 120 N
m₂ = 3.25 kg, F₂ = 120 N
m₃ = 5.5 kg, F₃ = 120 N
m₄ = 4.5 kg, F₄ = 120 N
Hence, it can be seen that the highest acceleration is of rocket 2.
Answer: C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
Explanation:
The speed of each car is defined as:
where d is the distance traveled by the car and t is the time taken.
For the yellow car, d=400 mi and t=8 h, so its speed is
For the green car, d=400 mi and t=10 h, so its speed is
So, the correct choice is
C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
