JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
Two balls A and B are placed at the top of 180 m tall tower. Ball A is released from the top at t = 0 s. Ball B is thrown vertically down with an initial velocity 'u' at t = 2 s. After a certain time, both balls meet 100 m above the ground. Find the value of 'u' in ms 1. [use g = 10 ms 2] :
- A10
- B15
- C20
