James Bond drives his car at 100 mph out of the rearward-facing cargo door of an airplane that is flying at 300 mph relative to the ground. How fast and in what direction is his car moving relative to the ground?
Let us say plane is flying in the eastward direction !!
vcp = - 100 i^ mph
vpg = + 300 i^ mph
Velocity of car w.r.t ground, vcg = vcp + vpg
vcg = - 100 + 300 i^ mph
vcg = 200 i^ mph
Speed relative to ground = 200 mph,
Direction : -In the direction of plane !!

Question 3 PFlag question Points out of 100 Not yet answered A car drives horizontally off a cliff. The cliff is 15.7 m tall and the car travels 26.5 m horizontally before striking the ground. How fast was the car the top of the cliff? traveling at the moment it left Select one: a. 16.5 m/s b. 14.8 m/s c. 232 m/s d. 20.9 m/s e. 392 m/s
Zero Launch Angle - Car Drives Off a Cliff A car drives straight off the edge of a cliff that is h =40 m high. The police at the scene of the accident note that the point of impact is d =86 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as positive y-direction. A....
1. You are driving down the freeway at a constant 60 mph (26.8 m/s)·There is a truck in tot of you, and you estimate that every second you get 1 m closer to the truck. How fast is the truck going (in miles per hour)? 2. What is the velocity of the truck relative to you? Take the forward direction (the direction you are going in) to be positive 3. You are on an airplane and the flight screen informs...
A car cruises along a winding road 100 feet behind a slow moving tractor. The travel together at 30mph until they reach an empty straight away. Passing, the car accelerates at 25ft/sec^2 until it is 100 ft ahead of the tractor. a. Using the tractors position when the passing begins as reference, write expressions for the car and tractors positions as functions of time. b. Combine the two functions to obtain the relative position of the car with respect to...

1) To test the null hypothesis in the James Bond experiment (test his claim that he can taste the difference between a Martini that is shaken and one that is stirred) you have him taste 8 shaken martinis and 8 stirred martinis, presented in a random order. How would you interpret the results of the experiment if he was correct on 0 (zero) out of 16 times? 2) An experimenter expects an effect to come out in a certain direction....
Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
Tom has an initial wealth of 100. His car may be stolen so he runs a risk of a loss of 40 dollars. The probability of loss is 0.2. It is possible, however, for Tom to buy insurance. One unit of insurance costs γ dollars and pays 1 dollar if the loss occurs. Thus, if α units of insurance are brought, the wealth of Tom will be 100-γα if there is no loss (a good state) and 100-γα-40+α if the...
2. An airplane is heading due north at an airspeed of 950 km/h, but there is a constant wind blowing from the northeast at 100 km/h. We will use vectors to work out how far off course the plane is blown, and what its ground speed is. (a) Write down a vector, p, that represents the intended flight path of the plane in one hou. (b) Write down a vector, w, that represents the movement of a particle caught in...
