(a) A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 32° ramp at a speed of 40.0 m/s (144 km/h). How many buses can he clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 20.0 m long? (b) Discuss what your answer implies about the margin of error in this act—that is, consider how much greater the range is than the horizontal distance he must travel to miss the end of the last bus. (Neglect air resistance.)

Which of the following are TRUE? Choose only three (3). Select one or more: a. At constant launch angle, maximum height decreases as initial velocity increases. The maximum height is inversely proportional to the square of the initial velocity. b. At constant launch angle, range increases as initial velocity increases. The range is directly proportional to the square of the initial velocity. c. At constant launch angle, maximum height increases as initial velocity increases. The maximum height is directly proportional to the square of the initial velocity. d. At constant launch angle, range decreases as initial velocity increases. The range is inversely proportional to the square of the initial velocity. e. The time of flight is directly proportional to the initial velocity. At constant launch angle, time of flight increases as initial velocity increases.  f. The time of flight is inversely proportional to the initial velocity. At constant launch angle, time of flight decreases as…

An airplane takes off and flies upward at an angle of 21° with a constant speed of 262 m/s. While the plane is flying upward, a piece of the engine falls off when the plane reaches a height of 860 m. a) How long does it take the piece of the engine to reach the ground? Give your answer in seconds. b) What is the horizontal distance covered by the piece of the engine before it lands? Give your answer in meters.
