calculate the impulse to stop a 1500kg car moving 90kmper hours
Answered by drwls
Convert 90 km/h to 25 m/s, and multiply that by the mass,in kg.

The impulse required equals the initial momentum. The units should be kg*m/s
Answered by kretheka
given:
v=90km/h=90*5/18=25m/s.
mass=1500kg.
solution;
impulse=1500*25=37500kgm/s
