Answer:
The answer should be C. some mass was consumed in the reaction
Answer:
a) = 1.35 10⁴ N
, b) F = 1.35 10⁶ N, c) F / = 100
Explanation:
a) Let's start by calculating the aceleration it takes for the person with a seat belt and air bag to stop, the approximate distance between the floor and the steering wheel is about 50 cm, let's use kinematics to calculate the acceleration
v² = v₀² - 2 a x
0 = v₀² - 2 a x
a = v₀² / 2 x
a = 15² / (2 0.50)
a = 225 m / s²
We calculate the force with Newton's second law
F = m a
F = 60 225
= 1.35 10⁴ N
b) we perform the same calculation for a person without a belt
a = v₀² / 2x
a = 15² / (2 0.005)
a = 22500 m / s²
F = m a
F = 60 22500
F = 1.35 10⁶ N
c) let's calculate the relationship between these two forces
F / = 1.35 10⁶ / 1.35 10⁴
F / = 10²
Answer:
40
Explanation:
because of the force acting on it
Answer:
Please see list of answers below
Explanation:
If the FORCE applied to the car doubles, then following the equation F = m * a , the acceleration will DOUBLE as well.
The mass of the car stays the SAME.
And the velocity of the car will INCREASE with time based on the formula of kinematics of an accelerated object:
v(t) = vi + a * t
The solution for this problem is:The charge would be now equal to:(electric constant) multiplied by the (field strength) multiplied by the (area) so plugging in our values, will give us:8.85 * 10^-12 As / (V * m) * 3 * 10^6 V/m * 0.055 m^2 = 1.46 e-6 amperes would be the answer
