Answer:

Explanation:

Using E= hc/wavelength

6.63 x10^-34 x3x10^8/ 236nm

19.86*10^-26/236*10^-9

=0.08*10^-35Joules

A 9500 kg boxcar traveling at 14 m/s strikes a stationary second car. The two stick together and move off with a speed of 6.0 m/
jasenka [17]

<u>Answer:</u> The mass of the second car is 12666.7 kg

<u>Explanation:</u>

To calculate the mass of car, we use the equation of law of conservation of momentum, which is:

m_1u_1+m_2u_2=(m_1+m_2)v

where,

m_1 = mass of car 1 = 9500 kg

u_1 = Initial velocity of car 1 = 14 m/s

m_2 = mass of car 2 = ? kg

u_2 = Initial velocity of car 2 = 0 m/s

v = Final velocity = 6.0 m/s

Putting values in above equation, we get:

(9500\times 14)+(m_2\times 0)=(9500+m_2)6.0\\\\m_2=\frac{9500\times 14}{6}-9500=12666.7kg

Hence, the mass of the second car is 12666.7 kg
