Question
The head of SPECTRE has devised a fiendish plot to liquidate his mortal enemy 007; he will cause a toxic rain to fall on the deserted valley where the intelligence agent 56 Special relativity agent is staying with a companion. Fortunately Mr. Bond's latest bag of tricks contains an umbrella. the rain falls at a speed of 10 m/sec, at what angle with the vertical must 007 hold the umbrella to stay dry as he and his companion run at a speed of 10 miles/hr to catch the next bus out of the deserted valley? A star in the sky is observed from earth to describe an elliptical path whose minor axis subtends an angle of 36". What angle docs the star make with the ecliptic?Explanation / Answer
Velocity of Rain = - 10m/s j^
Velocity of man = 10 miles /hr = 4.47 m/s i^
To stay dry they have to tilt umbrea by angle, "a" degrees with reference to the vericle direction.
Value of the angle "a" is calculated below -
a = tan^-1(4.47/10)
a = 24.08o
They must hold the umbrella at angle relative to vertical , a = 24.08o
