A ball is suspended by a thread from the ceiling of a car. The brakes are applied and the speed of the car changes uniformly from 10 m/s to zero in 5s. The angle by which the ball deviates from the vertical (g = 10 m/s2) is:
- \(\tan ^{-1}\left(\frac{1}{3}\right)\)
- \(\sin ^{-1}\left(\frac{1}{5}\right)\)
- \(\tan ^{-1}\left(\frac{1}{5}\right)\)
- \(\cot ^{-1}\left(\frac{1}{3}\right)\)
Answer
(C) ^ -1 ( 1 5 )
