Nookie1986 [14]

Answer:

2240.92365 m/s

Explanation:

$m_1$ = Mass of electron = $9.11\times 10^{−31}\ kg$

$v_1$ = Speed of electron = $5.7\times 10^7\ m/s$

$p_2$ = Neutrino has a momentum = $7.3\times 10^{-24}\ kg m/s$

M = total mass = $2.34\times 10^{-26}\ kg$

In the x axis as the momentum is conserved

$Mv_x=m_1v_1\\\Rightarrow v_x=\dfrac{m_1v_1}{M}\\\Rightarrow v_x=\dfrac{9.11\times 10^{−31}\times 5.7\times 10^7}{2.34\times 10^{-26}}\\\Rightarrow v_x=2219.10256\ m/s$

In the y axis

$Mv_y=p_2\\\Rightarrow v_y=\dfrac{p_2}{M}\\\Rightarrow v_y=\dfrac{7.3\times 10^{-24}}{2.34\times 10^{-26}}\\\Rightarrow v_y=311.96581\ m/s$

The resultant velocity is

$R=\sqrt{v_x^2+v_y^2}\\\Rightarrow R=\sqrt{2219.10256^2+311.96581^2}\\\Rightarrow R=2240.92365\ m/s$

The recoil speed of the nucleus is 2240.92365 m/s

An occupant of a car has a chance of surviving a crash if the deceleration during the crash is not more then 30 g. Calculate the

sweet [91]

Answer:

20,850 N

Explanation:

We can solve the problem by using second Newton's Law:

$F=ma$

where

F is the force

m is the mass

a is the acceleration

In this problem, we have:

m = 70 kg is the mass

$a=-30 g=-30 (9.8 m/s^2)=-294 m/s^2$ is the acceleration (which is negative, because it is a deceleration)

So, we can use the equation above to find the force:

$F=(70 kg)(-294 m/s^2)=-20580 N$

and the negative sign simply means that the force is in the opposite direction to the motion.
