A runner wants to finish a 400 m race in 46 seconds. He accelarates from rest and attained his maximum velocity in 6.7 seconds. He then continue running the race with his maximum velocity until he finished the 400m race. What is his constant maximum velocity in m/s? Round off your final answer to three decimal places.

Q16. A 3.4-kip car speeds up uniformly from 0 to 57 mph in 39 seconds up the 15⁰ incline. If the engine has an efficiency of e = 0.73, what is the power input (in hp) when the car's speed reaches that final speed? (1 hp = 550 ft-lb/s) Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. Take g = 32.2 ft/s². Your Answer: Answer 15°
4) You were leisurely flying your F-18 when you encounter an alien aircraft. The alien was flying at an altitude of 3 km while you were at an altitude of 600 m. You begin to increase your speed at a rate of 2.0 m/s?. You are traveling at a speed of 750 km/h at the instant when 0 = 45° and at the same instant the alien has a constant velocity of 1,500 km/h. a) Determine the velocity and acceleration vectors (in m/s and m/s², respectively) of the alien as observed by you. [Ans. to Check: VB/A = 208.4 įm/s] b) Determine the time rate of change of the vector r that is between you and the alien ship in m/s. In other words, find r. [Ans. to Check: i = 147.32 m/s] Hint: Do not forget about your ability to dot in different directions to eliminate variables from the equation. c) Calculate the angular velocity of the spaceship relative to you in rad/s. d) Determine the radial and angular accelerations in m/s? and rad/s². [Ans. to Check: ï = 4.86 m/s²] VB 3 km VA 600 m
