An 80.0 kg running back was traveling 6.0 m/s before he gets hit. The 100.0 kg linebacker who hit him was running 4.5 mls in the opposite direction a. What was the momentum of the running back before the collision?

b. What was the momentum of the linebacker before the collision?

c. What was the total momentum of the combination before the collision?

d. Assuming they stick together after the collision, what direction will the
combination travel?

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

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.
