Many people have some sense for the SI units describing mass, length, and time. one kilogram is roughly the mass of a typical sports water bottle (when full) one meter is roughly the height of a kitchen counter one second is a typical time interval between heartbeats (when at rest) But the momentum unit we just learned—the "kilogram meter per second"—is another matter! How many kg · m/s might describe the following everyday phenomena? (Recall that momentum equals the product of mass and velocity.) a 0.05 kg (50-gram) tennis ball crossing the court at 20 m/s (about 45 mph) _____________ kg · m/s a 50 kg (110-pound) teenager jogging at 2 m/s   about 4 1 2 mph  .  _______________kg · m/s a two-ton SUV (2,000 kg) following a dirt road at 5 m/s (about 11 mph).  ________________kg · m/s

Many people have some sense for the SI units describing mass, length, and time.
  • one kilogram is roughly the mass of a typical sports water bottle (when full)
  • one meter is roughly the height of a kitchen counter
  • one second is a typical time interval between heartbeats (when at rest)
But the momentum unit we just learned—the "kilogram meter per second"—is another matter!
