1. what is the mass of 20.0 liters of diesel fuel? assume the fuel has a density of 0.85 g/ml. 2. what is the molecular weight for a teflon monomer, tetrafluoroethylene? 3. what is the structural formula for methyl alcohol? 4. glycerol is sometimes added to candy to keep it soft; it has a structural

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
