Chapter 3, Problem 28PE
(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.)

A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a ramp of 61.8 degrees at a speed of 49 m/s. What would be
the largest number of buses he can clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 10.0 m long? Use g = 9.8 m/s?. Your
answer should be in the form of an integer number (e.g., 3 buses, not 3.4 buses).

A very bored 318 kg bear decides to jump across a stream. The stream is 6 m wide and the east bank of the stream is 1m higher than the west bank (where the bear starts). The bear can jump with an initial velocity vi(4m/s, 4m/s) , and decides to start from 3 in the air, halfway up a sturdy tree. If the origin is at the bear's foot (up in the tree), write an equation describing the coordinate of the bear while it is in the air. Use the following table as a reference. Note that it may not be necessary to use every variable. For Use t g

The largest of these could throw a 300 kg stone a distance x = 2 km. Assume that the stone was launched at an angle of 0 = 45 degrees above the horizontal; in the absence of air resistance, this gives the largest range. a) What speed did the stone have to be launched at to achieve this range? b) How long was the ball in the air? c) How fast was the ball traveling at the apex of its flight?arrow_forwardThe cannon on a battleship can fire a shell a maximum distance of 32.0 km. Calculate the initial speed of the shell in meters per second. Neglect air resistance to make the problem easier.arrow_forward

- James Bond runs then jumps off a building in a horizontal direction at speed v. He tries to reach the roof of a building nearby, at a distance d = 10 m. (a) That building is 10 m shorter than the one where Bond jumps off. If his speed cannot exceed 10 m/s and his initial velocity is purely horizontal, does he have a chance to make it? If yes, what is his minimum requiredspeed? (b) Consider instead what happens if the building he jumps to has the same height as the one he jumps from but this time he jumps with some initial angle q.
