Lindsey P asked:
If one vehicle driving 30 meters/second collides with another travelling in the opposite directing at 20 meters/second in a front end collision, assuming they both have a mass of 1000 Kg, what is the resulting velocity?

If one vehicle driving 30 meters/second collides with another travelling in the opposite directing at 20 meters/second in a front end collision, assuming they both have a mass of 1000 Kg, what is the resulting velocity?
Tour guide
m_1= 1000kg m_2= 1000 kg
v_1= 30 m/s v_2= -20 m/s
This is a momentum problem.
m_1v_1+ m_2v_2 = (m_1+m_2) v_f
1000(30)+ 1000(-20)= (2000)v_f
10000/2000= v_f
v_f=5 m/s in the direction of the first vehicle.
