A ball is thrown upwards from the ground with an initial velocity ‘u’.The ball is at a height of 60 m at two times,the interval being 6 s.Find the initial velocity ‘u’
Solution: First Method: The ball reaches the given height of 60 m at a time t 1 seconds ( rising up).For the second time it reaches the 60 m height at a time t 2 seconds. (comes down) Applying the equation of motion with the sign convention. Initial velocity (u) = +u Acceleration due to…

Calculation of Resultant Force Angle | 120° Solution
Question: Two equal forces have their resultant equal to either.At what angle they are inclined? Solution: Resultant force Angle $$R=\sqrt{A^2+B^2+2AB Cos\theta}$$ Let the two forces be represented by A and B and their resultant is R. Here A=F, B=F and R=F; Reason: the given two forces are equal and their resultant is equal to either.…
