1.	A ball is suspended by a thread from the ceiling of a tram car. The brakes are applied and the speed of the car changes uniformly from 36 kmh^(-1) to zero in 5 s. The angle by which the ball deviates from the vertical is (g=10 ms^(-2))
Answer» `TAN^(-1)((1)/(3))` `SIN^(-1)((1)/(5))` `tan^(-1)((1)/(5))` `cot^(-1)((1)/(3))` Solution :`v=u+at , tan THETA=(a)/(g)`
