To be able to determine the original speed of the car, we use kinematic equations to relate the acceleration, distance and the original speed of the car moving.
First, we manipulate the one of the kinematic equations
v^2 = v0^2 + 2 (a) (x) where v = 0 since the car stopped
Writing the equation in such a way that the initial velocity or v0 is written on one side of the equation,
<span>we get v0 = sqrt (2(a)(x))
Substituting the known values,
v0 = sqrt(2(3.50)(30.0))
v0 = 14.49 m/s
</span>
Therefore, before stopping the car the original speed of the car would be 14.49 m/s
The first successful flyby of Venus was performed by NASA's Mariner 2 spacecraft on 14 December 1962, following failed attempts by both the Soviet Union and the USA. The first successful landing was the Soviet Venera 4 lander, which touched down on the surface on 18 October 1967
Answer:
12,46
Explanation:
esto se debe a que el número que está después del 5 en este caso 5 aumenta o eleva el valor aunque si es un número menor a 5 queda igua
Answer:
the tempature and the map and climate
Explanation
Answer:
7.37 kg
Explanation:
By Newtons Second Law of Unbalanced Forces
Force = Mass × Acceleration
140N = Mass × 19m/s^2
Mass = 140N / 19m/s^2
= 7.37 kg
