1. A student found a large rectangular wooden box that measures 2.35 m long, 1.05 m wide, and 0.500 m deep. He wants to invite a few friends to float in the river. How many 78.0 kg students can the boat safely carry? (The answer may surprise you, and then you would be creative to load these students.)

2.Calculate the linear momentum (in kg m/s) of a pickup truck that has a mass of 935 kg and is traveling eastward at 27.0 m/s.

3.Taking the density of air to be 1.29 kg/m³, what is the magnitude of the angular momentum (in kg m²/s) of a cubic meter of air moving with a wind speed of 73.0 mi/h in a hurricane? Assume the air is 50.2 km from the center of the hurricane "eye."
