Answer:
Can you give me brainliest
because I need it in order to rank up.
Explanation:
Answer:
-7500 N
Explanation:
v₀ = 108 km/h = 30 m/s
v = 0 m/s
t = 4 s
a = Δv / Δt
a = (0 m/s − 30 m/s) / 4 s
a = -7.5 m/s²
F = ma
F = (1000 kg) (-7.5 m/s²)
F = -7500 N
<span>The melting and freezing points of a substance are the same.
Substances melt and freeze at the same temperature. Hope this helps! :)</span>
We could determine the acceleration using this formula
Given from the question v₀ = 23 m/s, v₁ = 0 (the car stops), t = 5 s
plug in the numbers
a = -4.6
The acceleration is -4.6 m/s²
Answer:
Yes. Walking is controlled falling because you need to let go in order to move forward. If you never let your foot fall, your movements would be stilted and robotic. And according to medical engineers," When we walk normally we are constantly correcting tiny falls to keep ourselves stable."
