Formula for acceleration: a = v-v0/t
a is acceleration, v is final velocity and v0 is starting velocity, t is time
Now plug it in
a = 50m/s - 30 m/s = 20 m/s/ 5s = 4 m/s^2
The acceleration is 4 m/s^3
Answer:
the statements the correct one is A
Explanation:
Let's analyze this exercise, vehicles have the same mass and speed, so we can use the momentum impulse ratio
I = ∫ F dt = Δp
the Δp is the same for both cars since they have the same mass and the same speeds, so the momentum is the same in both vehicles
When they indicate that vehicle A was reduced more than vehicle B, this implies that the force acted for a longer time, to have the largest reduction in size, therefore the impact force was less in car A than in car B
Resisting the statements the correct one is A
Nicolaus Copernicus
This theory was first proposed by Nicolaus Copernicus. Copernicus was a Polish astronomer. He first published the heliocentric system in his book: De revolutionibus orbium coelestium, "On the revolutions of the heavenly bodies," which appeared in 1543.
