The weight of the car in the picture of the computer screen is 9,800 Newton's.
Answer:
21828 m
Explanation:
= speed of sound through ground = 6 km/s = 6000 m/s
= speed of sound through air = 343 m/s
t = time taken for the vibrations to arrive
t' = time taken for sound to arrive = t + 60
d = distance of the point of explosion
time taken for the vibrations to arrive is given as
eq-1
time taken for the sound to arrive is given as
using eq-1
d = 21828 m
That all depends on the planet toward which the mass is falling.
If this happens to be taking place near the Earth, then the object accelerates
at the rate of about 9.8 meters per second every second.
Furthermore, if there is truly no air resistance, then it makes no difference whether
the object is a feather, a mass of 30 kg, or a school-bus. All objects accelerate at
the same rate regardless of their mass.
Answer: 6N
Explanation:
F = MA due to Newton's second law
M = 2
A = 3
plug in to get
F = 2 * 3 = 6N
