Question

Detail as below:

Consider two cars, one a compact model (m = 768 kg) and the other an SUV (m = 2457 kg). The SUV is traveling at 16 m/s, while the compact car is traveling at an unknown speed v. If the two cars have the same momentum, what is v? m/s? Two particles of mass mi = 1.8 kg and /t?2 = 2.3 kg are traveling with velocities = 4.7 m/s, and v2 = 2.5 m/s as shown in the figure below. What is the total momentum of this system? Be sure to give the magnitude and direction of the momentum, magnitude

Explanation / Answer

1) 768*v=2457*16

==> v=51.187

2) total momentum=1.8*4.7 i +2.3*2.5 j=8.46 i +5.75 j

==> mag=10.229

direction=34.20 degrees above X-axis
